HZWB-231 temperature transmitter

1、 Product Overview

The HZWB-231 series temperature transmitter product uses Pt100 thermistor as the signal measuring element, and is automatically measured by a computerDynamic testing was conducted using laser impedance tuning technology for zero point and sensitivity temperature compensation over a wide temperature range. The amplification circuit is located in stainless steelInside the steel casing, the sensor signal is converted into a standard output signal, fully leveraging the technological advantages of the sensor to enable the 133 seriesThe column temperature transmitter has excellent performance. It has strong anti-interference, overload and impact resistance, small temperature drift, and high stability,It has high measurement accuracy and is an ideal pressure measuring instrument in the field of industrial automation.

2、 Working principle

The temperature sensor generates a differential resistance signal in PT100 when the temperature of the measured medium (gas or liquid) changesThe signal corresponding to the range is converted into a standard analog signal or digital signal through a dedicated amplifier.
