Q: Are your products “Made in the USA”?
A: We pride ourselves on being an “American” company but, due to the realities of global electronics manufacturing, federal law prevents us from putting an unqualified “Made in the USA” on our products. We can make the following claims however. All of our Products are designed, engineered and assembled in the USA, our electronic components are sourced from Europe, Asia and the USA. All machining is done in the USA.
Q: Are RIFE sensors compatible with (insert fluid here)?
A: All of our sensors are designed with the racecar market in mind, as such, they are compatible with all commonly used automotive fluids. All of the wetted parts in our sensors are manufactured out of 316 stainless, Viton and anodized aluminum. For E85, Ethanol and Methanol fuels we use a Parker-Hannifin material explicitly designed for the application. Sensors equipped with this material are denoted with an “F” after the sensor range on the sensor body. If there is any question, contact the fluid supplier or us here at the factory.
Q: I have a Teal/Orange thing going on in my engine compartment, are custom colors available?
A: All of the coatings on our parts are there for performance reasons, if you would like a custom coating, please contact the factory to discuss.
Q: What should I use for connections/hoses?
A: Whenever practical, we recommend -3AN braided hoses, these have proven to be durable, reliable and leak-free when properly installed/routed. There are manufacturers that make -2 hoses with -3 ends, these are also perfectly acceptable and may save some weight. There are certain applications where the 1/8 NPT ports are advantageous, such as push-lock fittings, EMAP applications or anywhere a pressure snubber is required.
Q: When would I use a pressure snubber?
A: pressure snubbers are use to protect the sensor from transient pressure spikes that could damage the sensor diaphragm. The most common automotive use we come across is for measuring exhaust manifold pressure (EMAP) on turbo applications. Although the average pressure may be, say, 45 psi, when the exhaust valve opens, the pressure may spike significantly for a few milliseconds. The pressure snubber blocks that spike, protecting the sensor while allowing the sensor to continue reading the “average” pressure. If you have any questions about your particular application, give us a call.
Q: I am worried about my molded sensor cables, what is their temperature rating?
A: All of RIFE sensor cables are constructed with a PUR (polyurethane) jacket. PUR remains flexible and tough in a temperature range of -40F to 260F. We recommend that you try to route all cables away from heat sources wherever possible. If distance isn’t practical, we recommend the sensor cable be covered with high temperature braided loom.
Q: what is the minimum wall thickness for installing the ¼-28 threaded temperature sensor?
A: At a minimum, we like to see 3 complete threads of engagement, especially in boosted applications. This works out to just over .100” for ¼-28 thread. To be safe, let’s say an 1/8 of an inch. If the piping is thinner, there are 2 options: a) install a weld bung, or (b)build up the area with a bit of weld, grind flat, then drill and tap. It should also be noted that we do not recommend installation into tubing less than 2” in diameter without first providing a flat surface for the O-ring .
Q: What are the 4 and 6 pin wiring harnesses made of?
A: All of our wiring harnesses utilize genuine Deutsch connectors and pins. The wire is Mil-Spec M22759/32. The 4 and 6 pin wire harnesses both use 20AWG wire.
