1134.05E Oktober 2005WATER PRESSURE TRANSMITTER VPL 16Water pressure transmitter VPL 16 is designed to detect pressures at the HVAC applications; water, heating, air-conditioning and refrigeration systems. Pressure sensor element is made by using ceramic technics. Allowed mediums are water, air, oils and glycol/water mixtures. Outputs (0-10Vdc or 4-20mA) are directly proportional to the pressure inside the pipeline. Material of wetted parts is stainless steel (AISI 303) and housing for electrical connections is made of heat resisting plastics. When the transmitter is connected to the cold / chilled water circuit, condensation on the sensor must be prevented. The range for measuring can be chosen at commissioning. The socket for display is ready installed on the card. The cover with display can be added afterwards. Possible drifting of the zero point can be eliminated by pressing about 8 s the ”zero” button inside the device. Red light comes on. When making this zeroing the sensor must be without pressure.
