Features:
1, High reliability and exceptional EMC performance: Built-in multi-level protection circuit for high reliability.
2, High-voltage isolation: As high as 1000V for the isolation voltage between metal capacitance sensor processing circuit and main circuit.
3, HVRT communication protocol: PC programmable
4, High performance-price ratio: HVRT digital bus communication, low price, high precision, good quality.
5, Easy to install and reliable with unique design.
6, HVRT protocol is a proprietary communication protocol developed by our company, based on the voltage modulation. Similar as HART communication protocol.
7, These are recommended in application requiring amplification of RTD or T/C signals to carry to a long distance or guard against heavy field electrical noise. The transmitter converts various input to an analog signal for direct interface with Indicators, recorders, controllers, PLC, DCS, systems can be used for a wide range of applications in process control, automatic machinery and hydraulic or pneumatic system.
