Off-Highway Sensors for the 5 V Range

Non-contact off-highway sensors provide precise, reliable measurements that fit seamlessly into applications that previously relied on potentiometers and already have 5 volts running to the location.

The Temposonics® M-Series MH off-highway sensors are now available with 5-, 12-, and 24 V input supplies. The 5 V MH model sensors come in both ratio-metric and fixed-reference output styles with a 0.25 to 4.75 V signal output. The ratio-metric output option mimics the natural output of a potentiometer, while the fixed-reference output is referenced to a fixed voltage and does not swing with variations of the vehicle supply voltage, eliminating the subsequent measurement errors that occur as a direct result of inconsistent input voltage.

Said Brian Cox, MTS Systems Corp., “We anticipated the ratio-metric version to be more popular for replacing potentiometers, but what we have found is that in many applications the potentiometers were being treated as a fixed-output sensor and any variation in the supply voltage was adding to measurement error. With the fixed-reference output, the variation due to supply fluctuation can be completely eliminated.”

The sensors feature a 100g shock and 25g vibration resistance rating as well as 200 V/m EMI protection. They fit cylinders 2 in. in diameter or larger. Stroke range is 2 to 98 in. (50 to 2,500 mm), in temperatures ranging from -40° C to +105° C.
