Optimal monitoring of relevant process parameters is essential for increasing the efficiency of pneumatic processes and conserving resources. That’s why SICK offers a wide range of electronic pressure transmitters and pressure switches.

The PAC50 electronic pressure switch is designed for pneumatic applications. Thanks to its three large function buttons and large display, it is easy to use. Processes are very easy to read on the display: The colors of the digits change when the set switching points are reached. This means the respective output state can be recognized even from a distance. The PAC50 can be used flexibly thanks to its measuring ranges for positive and negative pressures. The pressure switch is also produced free of paint wetting impairment substances (PWIS-free). The PAC50 has a dust- and waterproof housing. In addition, the optional IO-Link interface ensures good networking. – Impressive advantages.

In factory automation, compressed air is among the most expensive forms of energy. To save costs, you must ensure that leaks in compressed air systems are detected as quickly as possible.

The PAC50-FGG (Leakage Tester) variant provides a cost-effective solution for detecting leak in compressed air systems. Basically, the sensor monitors the pressure drop over a preset period of time. The pressure switch enables a high degree of automation while doing so: The measurements can be started either automatically via a PLC or manually. The PAC50-FGG controls a valve via the output signal, puts the system in a locked state, and shows on the display the pressure drop, the period of measurement and – if the volume of the measured system is known – also a leakage rate in L/min. Depending on the presetting of the pressure switch, a signal regarding the measured time period or the pressure difference can be output via the analog output. At the same time, the sensor also retains its function as a simple pneumatic pressure switch.
