Calibration
The pressure sensors are calibrated in the factory. If necessary recalibrate according to the calibration instructions.
Safety precautions and personnel protection
For the correct and safe use of this instrument it is important that the VDE (or similar association) safety precautions as
well as the safety precautions of the professional/trade association having liability for industrial safety regarding the operation
of electrical instruments and equipment be observed.
Installation
Using both straps the pressure sensors are connected to the mounting ttings. Avoid having interference sources (transformers,
transmitters, motors etc.) or heat sources in the neighbourhood. Shocks or vibrations at the mounting connection
can cause distortions to the output signals. Connections should be vertical, i.e. the pressure connections should point
downwards. The sensors are calibrated in the factory for such mounting conditions. In addition the formation of condensation
in the pressure tubing of the sensor is also reduced.
Preparations befor operation
Prior to operation remove the housing cover. Electrical connections are made using terminal connections. Take care when
connecting the power supply. Do not connect the power supply to the output connectors. Instruments with a DC power
supply are reverse-connect protected. The output signal of the sensors is short-circuit protected.
The pressure transducers of the DPS type series are suitable for detection of excess pressure, low pressure or differential pressure of non-aggressive gasses. Pressure measurement is carried out using CuBe membranes sensitive to the respective pressure
range. Using an inductive system the membrane systems are ‘force-free’ scanned.
Note: Commissioning may only be reliable, trained or assigned personnel.
