WTZd-285z/2Series Temperature Meters
Product Features:
The new generation of liquid pressure thermometers and the series of temperature instruments developed from them overcome the shortcomings of the original instruments, such as single performance, poor reliability, and large bulb volume. The volume of the temperature sensing element is reduced to 1/30 or 1/60 of the original. Innovatively, the sensor thermistor is installed inside the temperature sensing element, achieving an integrated electromechanical temperature measurement function. This forms a multifunctional and serialized range of temperature instruments based on liquid pressure thermometers, including remote transmission, explosion-proof, shockproof, corrosion-resistant, electrical contact, and temperature signal transmission capabilities.
