Temperature sensor has hot head remote to the electronics

Jan 2000 Sensors & Transducers

A large number of operating procedures often demand process temperatures of up to +200°C. High temperatures mean the end for most electronic devices - not so for Baumer Electric's capacitive CFAH series high temperature sensors.

Available locally from Temperature Controls, these sensors feel really 'at home' when things get hot. Target materials such as liquids, granulates, pastes and similar substances can be detected reliably even at very high ambient temperatures. Since conventional electronic components cannot stand temperatures of 100°C or more over longer periods, this sensor has simply been 'split' into a hot and cold zone. The actual 'hot' sensor head, which can be used at an ambient temperature of -40 to +200°C (optional up to 250°C), is made of chemical-resistant Teflon and stainless steel. It is connected remotely by a high-temperature-proof coaxial cable at a distance of 1 m from the oscillator and decoding electronics, which are installed in an environment of -25 to +75°C. The switching distance of the high temperature sensor is 15 mm and can be adjusted by the potentiometer, which is fitted with the indicating LED on the 'cooler' peripheral device.

Baumer's high temperature sensor CFAH is the ideal substitute for mechanical sensors in a wide range of applications. Due to its high chemical resistance, it can also be used in aggressive environments.
