Pressure Sensor mounting Solutions

Oil pressure mounting hose

Oil pressure hose. Required to avoid damage to the sensor. 4" length 1/8 NPT male / female ends

1/8" NPT 4 port sensor manifold. Pressure sensors should not be monted in engine block. 4 independent ports, each with 3 inlets/outlets, allows for the remote mounting of transducers which eliminates inaccuracies due to vibration and heat	Click to expand
This block is very flexable with 1/8 npt ports on 3 sides. It does comes with 4 1/8" NPT plugs for any unused ports. Typicaly mounted on the firewall with AN -3 or -4 hoses running to the pressure source.

Trans Pressure Sensor Mount

M-140

Pressure manifolds

WEB Price $65

Cushion mount for Transmission Pressure sensor. Includes 810-XP-HOSEEX. Does not include sensor.

 Pressure Sensor Facts

- A typical RP Vnet sensor (like oil pressure) consists of the Vnet module and the sensor.
- Cost of the two pieces is $250 but if you need to replace sensor component, the price is $179 (which is higher than some data logger companies and lower than others) also, if you can get generic industrial sensors they will work.
- Reliability of the sensor component should be the same as sensors supplied by by any data logger company using any brand quality industrial sensor. Pressure sensors actuall have a printed circuit board inside - see the pic below.
- RP single wire oil pressure sensors that come with the dash kits are problematic. RP supplies a soft mount kit for them which fixes most but not all problems. These sensors are $39 and and you get what you pay for.
- Harmonics are hard to quantify/measure - I have tractor pull guys and motorcycle land speed guys who can kill any pressure sensor in 15 seconds if mounted in the engine block. But lots of bracket racers guys get away with it.

- I scanned the WEB (11-10-11) and here is what I cam up with on pricing for various data logger pressure sensor prices: Autometer $179 (JEGS), RPM performance $107, $224 Altronics, $229 Computech and $179 Racepak. Some of those prices do include a cable so it's still not apples to apples.
- RP recommends soft mount of all pressure sensors.
- Generic sensors work on with Racepak V-net modules. The specs are 0-xxx PSIG, .5-4.5 volts output with a 5 volt supply and Packard connector. I sell them here - not trying to undercut RP sensor sales, just supply an alternative for guys who do have the sensor solid mounted - the wheelie bar sensor is an example of one that get beat up by some teams. You can Google or ebay search "pressure transducer xxx psi" then refine with the specs above if you want to search. You'll find there are 8 billion choices and I don't think it's worth your time.

How to mount pressure sensors. Pressure sensors can be damaged if mounted directly to engine blocks and other rigid pressure sources in your race car. In order to avoid damage, remote mount the sensor.
Use AN -3 line and 1/8" NPT -3 adapters to connect the sensor to your pressure source.   Thanks to Scott Smith, Montgomery Alabama for theses pictures!
