Product description
- ±500 Pa
- Accuracy: ± 13 Pa
- Modbus - not electrically isolated
- with display
PREMASGARD® 121x Calibratable Pressure Sensor - Modbus - SD (Series), with Modbus connection (Y-adapter), in an impact-resistant plastic housing with quick-release screws, connection ports for pressure hose (Ø 6 mm), with display, for measuring pressure (max. ± 500 Pa) in air. The International System of Units (SI) (default) can be switched to Imperial (via Modbus). Includes ASD-06 connection kit (2 m connection hose, two pressure connection nipples, screws). The pressure sensor is used to measure overpressure, underpressure, or differential pressure in clean air and gaseous media. It is used in cleanroom, medical, and filter technology; in ventilation and air conditioning ducts; in spray booths; in commercial kitchens; for filter monitoring and level measurement; or for controlling variable-frequency drives. A pressure sensor with a piezoresistive measuring element guarantees precise measurement results. The following parameters can be retrieved via Modbus: differential pressure [Pa] [inWC]. Modbus sensor SD with RS-485 Modbus interface (not galvanically isolated), switchable bus termination resistor, DIP switches for configuration when power is off, internal LEDs for telegram status indication (illuminated, individually programmable). The sensor is factory-calibrated; a specialist can perform a fine adjustment based on ambient conditions.
