High Accuracy 24VDC Temperature Sensor Transmitter Fast Response Time
Fast Response Time High Accuracy 24VDC Temperature Sensor Transmitter
Temperature Sensor Transmitter Working Principle
NT93420 temperature transmitter adopts thermocouple, RTD as temperature measuring element, the output signal from the temperature measuring element is sent to the transmitter module, which is converted into 4~20mA current signal 0-5V/0-10V voltage signal and RS485 digital signal output after the circuit processing of voltage stabilization and filtering, operation amplification, non-linear correction, V/I conversion, constant current and reverse protection, etc. with linear relationship with temperature.
Temperature Sensor Transmitter Design Feature
1. Simple installation, a variety of temperature measurement ranges to choose from.
2. Gas-liquid dual-use, compatible with 316L for any medium.
3. A variety of linear analog signals to choose.
4. Fast response time, high accuracy, compact and durable structure, strong anti-interference capability.
5. Good long-term stability, low energy consumption, small size.
6. Waterproof, explosion-proof, temperature resistant and shock resistant.
