Hex head threaded liquid temperature sensor

The 6001 Series is an industrial thermistor sensor line for use in a wide variety of liquid immersion applications but are usually mounted into pipes and tanks. The threaded metal housing reduces the stress on the sensor but still allows thermal contact with fluid. These threaded temperature sensors are designed for the most rigorous applications and provides a tight fitting seal to ensure accurate readings.

CTS can customize these sensors in a variety of ways to meet OEM requirements for probe length, cable length/color, sensor resistance value/accuracy, and connector type
