 Veritranz line of stainless steel replacement
     coolant level sensors for transit buses

 
 Veritech has designed and supplied stainless steel           
replacements for plastic coolant level sensors on transit buses.  
Our first device in this product line was developed to replace a
1/2" NPT plastic upper coolant switch used on NABI buses at
New Jersey Transit.  This resulted in an order for 1000 units from
       NABI Bus, many of which were installed at NJ Transit.  The part
       number for the latest version of this sensor is VT220794 and
       features the same independent sensor arm and float as our
       replacement for the OEM plastic sensor low coolant level sensor,
       our VT220594-D. There is a minimum order quantity of 25 units.

  
                     Replacement for Plastic OEM
                       Low Coolant Level Sensor
 
         In the Spring of 2015, we were alerted to problems with an
OEM plastic lower coolant level switch found on many NABI, New
Flyer, NOVA and Gillig buses from mid 2010 to the present equipped
with Cummins ISL9, ISLG, and ISB6.7 engines.  These
sensors have two main modes of failure that are addressed by
our replacement: false error coding and coolant leakage.  
An unreliable float design on the OEM sensor can allow the float
to hang upside down, indicating a critically low coolant level on a
surge tank that is full.  Our float moves in a single plane making
false coding nearly impossible. The OEM sensor may leak coolant
from the electrical terminals at the receptacle due to a large
difference in coefficients of thermal expansion between plastic
sensor and the stainless steel surge tank. Our device is
constructed of 304 stainless steel so it will not breakdown due
to thermal cycling.  The part number for this device is VT220594
and it will fit NABI, New Flyer, Gillig and NOVA buses.  After a
retrofit of the OEM plastic sensor with a epoxied harness plug and
Deutsch 2 way pigtail, we released our VT220594-D which is a
"plug & play" replacement.  These sensors are currently installed in
over 130 transit agencies in the US and Canada.  With over 9000
units installed, this device has a less than 0.4 % failure rate, nearly
100 times better than the OEM device it replaces.

    
    VT220694 3/8 NPT Coolant Level Sensor
 
 
     Veritech was approached by a transit agency who was having
problems with 1/4" plastic conductive coolant level sensors on their
2004 to 2006 New Flyer fleet after changing to a new extended life
coolant.  This coolant caused corrosion on the conductive surfaces of
the sensor and resulted in false error coding that caused engine derate.  
We traveled to the agency to examine the problem and develop a
solution.  After characterizing the resistance outputs of the sensor,
we found that there was a 3/8 NPT plugged port on the outboard
side of the surge tank and produced a prototype to utilize this port. 
The initial install was successful and the agency has since purchased
over 100 units.  

                    
 
                                        VT220638-C
 


          Veritech has now developed a 3/8 NPT replacment for the
Casco sensor for use on New Flyer transit bus surge tanks with the
plugged 3/8 NPT port on the outboard side of the tank and NABI CNG
buses with retrofitted surge tanks with 3/8 NPT instead of 1/4 NPT
original port size.  Currently 30 of these units are being evaluated at
LA Metro on their NABI CNG buses.
 
 
                                  VT220614-C
 

       Veritech's most recent coolant level sensor development is
a 1/4 NPT replacement for the Casco conductive sensor which was
used extensively on Cummins diesel engines from 2007 to 2012 and
has to be used on CNG applications on certain engines and bus models
of different OEMs since 2013.  We have had 4 units installed at LA Metro
on NABI CNG buses since March 2018 with no reported issues.  We have
just gone into production in order to satisfy orders from two transit
agencies looking to do more extensive evaluations.
 
 

                                 VT220738-O
 
        After being contacted by two agencies, each with a different
application for the same 3/8 NPT 3 wire optical switch, we began an
accelerated development of a new stainless steel coolant/hydraulic
fluid level sensor which could be used for a coolant level sensing
application on older New Flyer Invero buses and hydraulic fluid level
sensing on Low Floor Gillig buses.  The coolant level sensing application
was successful and the agency will order 10 units to start a replacement
campaign.  As soon as we have more information about the hydraulic
fluid level evaluation, I will update this entry.
 
 
                             Brake Pressure Switches
 
          Several transit agencies approached us in late 2017 regarding
problems with the 4 Psi and 7 Psi brake pressure switches installed
OEM on Gillig buses.  These plastic/metal switched have a separate
diaphragm and seal which can fail, allowing impurities from the air brake
system to enter the switch body causing contact failure.  On the 4 Psi
brake interlock pressure switch, if the switch fails to close, the system
will not read the minimum brake pressure and the bus will not move. 
We now have two part numbers for our US made welded chamber
stainless steel brake pressure switch, a VT260034 (4 Psi) and a
VT260037 (7 Psi).  We currently have units installed at two transit agency
customers and the unit is being evaluated by another West Coast agency.
 
 
                                 Oil Pressure Sensor
 

         In the past year, over 15 transit agencies have approached us
about issues they were having with the most widely installed transit
bus engine oil pressure sensor.  This device has had problems related to
oil passing through the sensor and leaking into the wiring of the engine
harness and failure of the sensing element which can result in a low or
zero oil pressure signal being sent to the ECM.  This can result in a road
call if the engine goes to a derate or shutdown condition.  We have
developed a US Made welded chamber stainless steel unit with an
integral Deutsch 3 way receptacle which will be shipped with the mating
plug kit for a complete retrofit.  Our first form, fit and function install is
already scheduled at a major Middle Atlantic transit agency and we have
nine other agencies ready and willing to evaluate the device.

Bus Maintenance Parts
      

        Veritech can help your Bus Maintenance people procure 
the right connectors, housings, pins, and sockets, as well as
many other electrical and electronic parts. We identify OEM
parts for our customers, helping them to avoid buying costly
components from the bus manufacturer. Often we can supply
parts for harness repair, avoiding high priced OEM cable assemblies.
      
        Veritech is providing many part solutions for NABI (North American
Bus Industries), MCI, Neoplan, and Setra buses and we are adding new
parts continuously.  We are providing the Philips Ecovision Long Life
H1, H3, and H7 halogen lamps rated from 3X to 4X, 1000 hours.
The H1 can be used as a direct replacement on the NABI daytime
running lamps and last considerably longer than competitors lamps.
We also offer an after-market high temperture head lamp harness for
these DTLRs.   Look to Veritech for LED replacments for many standard
incandescent lamps used on the buses to increase run time and lower
maintenance costs due to constant bulb replacement.
      
          Other electrical parts include a stainless steel liquid level sensor
for the coolant surge tank which dramatically outperforms the plastic unit
provided by the OEM.  Please contact us for more information on this and
any of our bus part offerings.  Below are pictured some examples of items
we have identified for our customers.

Bus Maintenance Cable Assemblies

& Harness Repair Kits

        Veritech can build replacement cable assemblies and harnesses, as well

as, harness repair kits and other customized solutions.  We are currently supplying

catalytic converter sensor harnesses, reading lights harnesses, and J1939

Diagnostic harnesses.  We also designed and supply an upgraded replacement

harness repair kit for low beam halogen head lamps.  Our latest harness

retrofit, a Water In Fuel (WIF) sensor harness for New York City Transit's

Orion VII diesel hybrid buses is pictured below.  Improvements were made

to the wire, teminals, connectors, and conduit to make a more reliable,

water tight assembly.
