New Low Coolant Sensor

Entratech Systems recently released a new low coolant sensor that has been under development for two years. The new sensor is designed for a variety of on and off road vehicles as well as marine applications. The sensor can be mounted in expansion tanks as well as heat exchangers and radiators, utilizing a high temperature, glycol resistant Polyphthalamide thermoplastic resin with a 3/8-inch pipe thread. The new sensor was designed around long life coolant applications that can plague typical conductive coolant sensors. Utilizing the low cost of conductive sensor technology and special circuitry to overcome plating problems, Entratech engineers have also incorporated the features of a power on self-test along with an EOL resistor for vehicle engine control computers to monitor sensor presence during operation. A low coolant condition will turn on an output power transistor, grounding a lamp load or signaling the engine ECU of a low coolant condition after a short delay to prevent false signals due to coolant sloshing in the tank. Surface mount technology and circuit filtering have made the sensor compatible with current vehicle demands for performance guided by SAE standards. The sensor operates on both 12 and 24 VDC electrical systems. Available from Entratech Systems, Sandusky, Ohio www.entratechsystems.com
