Product Description

PB8700 series integrated input type temperature and liquid level transmitter is composed of sensor, air-conducting cable and stainless steel cylinder. By measuring the temperature and pressure at the location of the sensor to test the temperature of the liquid and the height of the liquid level, and the liquid temperature and the height of the liquid level into the corresponding standard electrical signal output. Stable performance, good reliability, long service life, internal circuit design meets the requirements of intrinsic safety and explosion-proof, the maximum depth of water can reach more than 1500 meters, and its excellent performance, which is still the first of its kind in China, is specially designed for Sinopec's oil and gas wells exploration, and is used to measure the temperature and depth of water.
