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.
