Pressure, differential pressure and flow rate transmitter PREMASGARD 212

S + S Regeltechnik GmbH

Description

Pressure and differential pressure transmitters

The calibrateable, compact pressure sensors of the PREMASGARD® 212x series are equipped with 8 switchable measuring ranges, 2 switchable output signals (16 units in one) and optionally with display and are used for measuring overpressure, underpressure or differential pressure and air volume flows.

The piezoresistive measuring element is temperature compensated and ensures high reliability and accuracy. The pressure transmitters have a button for manual zero adjustment and an adjustable offset.
The pressure transmitters are used in clean room, medical and filter technology, in ventilation and air-conditioning ducts, in spray booths and large kitchens, for filter monitoring and level measurement or for controlling frequency converters. Measuring media of the pressure transmitters are clean air (non-condensing) or gaseous, non-aggressive, non-flammable media.

The pressure sensor has eight adjustable measuring ranges and thus minimises your type variety and stock-keeping with an increased range of application. The differential pressure sensor is incl. connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).


Measuring range pressure:

0 ... +50 Pa / -50 ... +50 Pa
0 ... +100 Pa / -100 ... +100 Pa
0 ... +300 Pa / -300 ... +300 Pa
0 ... +500 Pa / -500 ... +500 Pa
0 ... +1000 Pa / -1000 ... +1000 Pa
0 ... +2000 Pa / -2000 ... +2000 Pa
0 ... +3000 Pa / -3000 ... +3000 Pa
0 ... +5000 Pa / -5000 ... +5000 Pa


Output: 0 - 10 V or 4...20 mA

Duct humidity and temperature sensor incl. pressure and differential pressure transmitter PREMASGARD® 814x - Modbus

Maintenance-free microprocessor-controlled pressure transmitter PREMASGARD® 814x - Modbus (series) for exact measurement of relative humidity (0...100 % r.H). and temperature (-35...+80 °C) in ducts as well as for measurement of differential pressure (max. -7000...7000 Pa) in air. With Modbus connection, impact-resistant plastic housing with quick-release screws, optionally with/without display, with plastic sinter filter (replaceable). Incl. mounting flange and connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).

The pressure sensors are used to measure overpressure, underpressure or differential pressure in clean air and gaseous media. They are used in clean room, medical and filter technology, in ventilation and air-conditioning ducts, in spray booths and canteen kitchens, for filter monitoring and level measurement or for controlling frequency converters.

A long-term stable digital humidity and temperature sensor as well as a pressure sensor with piezoresistive measuring element guarantee exact measuring results. The following parameters are calculated internally from these measured variables and can be called up via the Modbus: Temperature [°C], relative humidity [% r.h.], dew point [°C], absolute humidity [g/m³], mixing ratio [g/kg], enthalpy [kJ/kg] (neglecting atmospheric air pressure), differential pressure [Pa], volume flow [/m3/h], air density [kg/m3].

Innovative Modbus sensors with galvanically isolated RS485 interface, switchable bus terminating resistor, DIP switches for setting bus parameters and bus address in de-energised state, LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated, individually programmable in 7-segment and dot-matrix range). The sensors are calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
