Mechatronic pressure measurement WIKA data sheet PV 34.83 ■ Hydraulics and mobile hydraulics ■ Plastics injection moulding machines ■ General machine building and plant construction ■ Media: Compressed air, neutral and self-lubricating fluids, neutral gases Special features ■ High vibration and shock resistance ■ Setting ranges -0.85 ... -0.15 bar and from 0.2 ... 2 bar to 40 ... 400 bar ■ Long service life due to high-quality micro switch ■ Precise switch point setting with adjustment knob Model PSM03 mechanical pressure switches in a diaphragm or piston variant open or close a circuit, depending on whether the pressure is dropping or rising. An adjustment knob enables easy, convenient and continuous setting of the required switch point. Optionally, WIKA offers its customers the factory setting of the switch point. Model PSM03 mechanical pressure switches are employed wherever compressed air, neutral and self-lubricating fluids or neutral gases are used and customers, due to their spatial conditions, have special requirements regarding the installation of the pressure switch. WIKA data sheet PV 34.83 • 06/2017 The high reproducibility of ±2 % of the switch point and the setting via the adjustment knob is interesting for customers for whom precision plays an important part. In addition, the individual orientation of the pressure switch makes the model PSM03 attractive for customers who set value on the adaptation of the switch to their specific space conditions.
