Pressure Difference Transmitter
The HT6 air pressure difference transmitter has a MODBUS/RTU-RS485 serial port. This device can be ordered in various ranges to measure the air pressure difference between two points. A voltage output channel of 0 to 10 volts (0 to 10 V) and a current output channel of 4 to 20 mA (4 to 20 mA) are placed on the device. Each analog output channel works independently and can be set to different values. Analog output values can be adjusted by software.
