Description
Overview
GAOTek protocol temperature calibrator uses the fieldbus technology and a new generation of smart fieldbus temperature transmitter, and it is an indispensable field device for process control. It integrates abundant function blocks and realizes not only general measurement function but also complicated control strategy.
Features
- Support thermal resistance and thermocouple sensors
- Thermal resistance supports 2 or 3-wire connection mode
- Thermocouple can use cold end compensation function
