Kavlico, a global business unit of Custom Sensors & Technologies (CST) has designed its EOP sensors to measure pressures in gasoline or diesel engines as well as other heavy-duty machinery. The sensors can be designed with a ceramic capacitive or piezo-resistive (PRT) sense element depending upon the application-specific requirement of the OEM.

Operating on 5 Vdc, the engine oil pressure sensor provides a linear amplified analog output proportional to pressure. These rugged devices are well-suited for hostile, high-vibration, high-noise environments. The ceramic capacitive versions are particularly capable of withstanding high over-pressure situations. The sensor utilizes Kavlico's patented ASIC electronic integration technology for extremely reliable and accurate signal conditioning.

Flexible by design, the lightweight version of this sensor (50 Grams or 1.76oz. Max.) can be configured with a variety of electrical and process media connections for easy system integration. Additionally, 316 stainless steel or brass packaging can be specified to insure further compliance with customer requirements.

The sensor pressure range is 0 to 300 psi gage or absolute reference. Proof and burst pressures vary with core technology used and housing materials, but may include a proof pressure of 3X upper Range Limit (URL) and a burst pressure of 5X URL. Common operating temperature is -40 to +125°C. Highly reliable, the sensor has an expected operational life of 10 million pressure cycles as well as a 10-year shelf life.
