The Series 685 Differential Pressure Transmitter is used to measure differential pressure and vacuum. The adjustable pressure range and output signal make it the ideal choice for installers and maintenance professionals. It has a user-configurable response time via a jumper and can be mounted in any orientation. Applications include building automation systems, clean room monitoring, valve and flap control, filter monitoring, and air flow control. It has an adjustable pressure range, a single button to zero, and can be reset to factory settings with a long button press. No additional reference pressure sources or separate calibration devices are necessary.
Product Applications
- Building automation, air-conditioning and clean room technology
- Valve and shutter control
- Filter, ventilator and fan monitoring
- Air-flow control
