PEL 1000 is a pressure transmitter for detecting pressures and pressure differences in air handling systems. The proper measuring range can be chosen at commissioning. The M models have RS-485 connection for Modbus RTU communication. ML-SER tool is needed at commissioning for making the Modbus settings.

The N models have a backlit display. The display resolution is 1 Pa. The display can be added also after commissioning. The measurement output (0…10 V, 2…10 V or 0…5 V) can be changed to control output by using the ML-SER tool. Accordingly, the controller settings can be changed by using the ML-SER tool. The zero point drift can be eliminated manually by disconnecting the tubes from the pressure inlets and by pushing the zeroing button on the board inside the device.

The 0…1000 Pa range is also used for the custom range setting. The custom range low limit value is 0 Pa and the high limit value can be changed with 50 Pa steps by using the ML-SER tool or via Modbus. Custom range minimum value is 0…100 Pa.
