Product Description

Applications: Monitoring of gaseous, non-combustible and non-aggressive media. Possible usage areas are:
- BMS and HVAC systems 
- Inside Pressure Measuring on Industrial Boilers, Furnaces and Dryers
- Bag-filter pressure monitoring
- Kiln draft pressure monitoring
Features:
~Setting ranges: Depending on type between -100 Pa and 1 bar

~Configurable pressure range: For an optimum adaptation to the application, the transmittercan be switched between various pressure ranges. The factorysetting is the most sensitive range. For the series 985M and 985A the less sensitive second range will be selected by simplyremoving a jumper. For the series 985Q the available eightranges can be selected by a rotary selector switch.

~Output signal selection:The output signal of the 3-wire version can be changed between 0 -10 Volt and 4-20 mA by removing a jumper.The series 985M is also available in a 2-wire version with 4-20 mA output signal.

~Configurable response time:The response time of the output signal can be configured using a jumper. If the jumper is in place the response time is slow (factory setting), which is useful for suppressing brief pressure peaks. If the application requires a fast response time the jumper must be removed.

~Easy offset calibration:The output signal of the 985M series can be calibrated to zero by pressing the MODE/Offset button in a pressureless state of the transmitter. The series 985A and 985Q perform an automated zero offset compensation.
