Electronic Pressure Switch

WIKA PSD-4 Electronics Pressure switch is the universal solution for industrial automation tasks – also in hygienic applications and under harsh conditions. Due to an accuracy of < ±0.5 % and minimal long-term drift, it permanently ensures an accurate representation of the process pressure for more than 100 million load cycles. The pressure switch is available with a digital output signal as well as a switchable and scalable analogue output. In addition, it can also be easily monitored via the self-diagnostics.

WIKA PSD-4 has large 14-segment display and red even in bright environments. In addition, the display`s content can be

turned through 180° and the case through > 300°. The PSD-4 Pressure Switch can be set via 3-button operation. Display and

menu offer intuitive navigation in accordance with VDMA specification 24574-1. This speeds up parameterisation and

reduces the installation effort.

Electronic Pressure Switch Model 711 is ideal for precise process pressure measurement. This Pressure Switch is built with high accurate piezo-resistive pressure sensor with 316SS diaphragm which is suitable for media like non-corrosive liquids and air. A wide range of pressure readings with optimum resolution are indicated through a large LCD display with back light. Two or Four independent setpoint is provided with SPDT relay output for on-off control function.

In addition, this instrument provides 4–20 mA DC analog current output. The output current range is programmable within the instrument calibrated range. Operational settings are done through 3 push switches accessible upon removal of cover or on the front through membrane keypad. The entire circuitry is housed in a cast aluminium, IP65 compliant weatherproof enclosure suitable for surface / wall (or) pipe mounting.
