New Airtex TPS Sensors

Airtex Engine Management has introduced what it describes as two “better-than-OE” non-contact throttle position sensors designed to eliminate wear issues and significantly reduce repair costs on Dodge Ram 2500 and 3500 diesel trucks.

The new Airtex TPS sensors, now available for 1998-2007 Ram 2500 (Airtex No. 5S5351) and 3500 (No. 5S5352) models, feature problem-solving “Hall Effect” integrated circuitry, which the company says eliminates the wear-intensive contact associated with some OE parts and aftermarket alternatives.

Repetitive motion of the contact fingers across the resistor board on conventional sensors can wear holes in the board, causing engine hesitation, according to Airtex. The company says its new innovative design eliminates this contact and also is significantly more resistant to shock and vibration.

Unlike competing sensors – including those offered by Dodge dealers – the new Airtex TPS sensors are sold without the mounting bracket, which the company explains is “expensive, and rarely needed.”

“A replacement mounting bracket is absolutely not needed in nearly all of these repairs, and it adds significantly to the cost of the parts sourced through dealers or other aftermarket suppliers,” said Glen Eichhorn, vice president, electronics, Airtex Engine Management. “By choosing Airtex, repair professionals can offer a better-than-OE alternative that also costs significantly less.”

New gas analysers launched

Cambridge Sensotec (UK) has enhanced its product range to offer EIGHT new gas analysers.

The new analysers are available with either an oxygen (O2) electrochemical sensor with a range of 0-100% O2 with an accuracy of ±1% of full scale, or the option of a low ppm electrochemical cell with a range of 0.1ppm-10,000ppm O2 with an accuracy of ±2% of the actual O2 reading.

The O2 sensor is individual or paired with a carbon monoxide (CO), carbon dioxide (CO2) or dewpoint sensor (H2O). Both CO and CO2 are measured using state-of-the-art infra-red sensors which have full pressure and temperature correction as standard. The infra-red sensors are available in a variety of ranges from ppm to percent. The H2O sensor is a high precision transmitter supplied with its own calibration certificate.

Each Rapidox 3100 gas analyser is fitted with an ultra quiet pump and is packed with features including fully programmable alarm circuits and analogue outputs, and easy calibration. Full data-logging software is included.
