HDP800 series pressure transmitter pressure sensitive core adopts high-performance silicon pressure resistance to fill the core. The internal ASIC conversion sensor's millivolt signal is converted into standard voltage, current or RS485 signal, with strong photoelectric isolation to ensure stable output. It can be directly connected to a computer, digital display or PLC. The current output mode can be used for long distance transmission. Cast aluminum explosion-proof housing, all stainless steel sealed structure, can be used in corrosive environment, has high vibration resistance and impact resistance. It is widely used in control, aviation, aerospace, automotive, medical equipment, HVAC and other fields.
The potentiometer is input to the safety barrier, and the 2-wire / 3-wire potentiometer signals in the danger zone are converted into current signals and output to the safety zone. This product requires independent power supply, and the three terminals of input, output and power are isolated. With online fault self-diagnosis function.
The RS485 digital communication signal from the danger zone is isolated and output to the safety zone, and the intrinsically safe power is provided to the instrument in the danger zone. Serial communication can be networked through a dedicated communication interface. This product requires independent power supply, and the three terminals of input, output and power are isolated.
The thermocouple / millivolt signal from the dangerous area is output 1: 1 to the safe area after isolation, and it can also output analog signals at the same time; it can be used with various types of thermocouples and weighing transmitters.
Analog output safety barrier, input 4 ~ 20mA current signal from safe area, output 4 ~ 20mA current signal to danger area through isolation, drive valve positioner and other equipment on site, and support HART signal bidirectional transmission. This product requires independent power supply, input, output and power are isolated at three terminals.
Output the resistance signal from the dangerous area to the safe area through isolation 1: 1. It can output two resistance signals at the same time, and it can also output one resistance and one analog signal at the same time.
