This is an electronic pressure switch and pressure transducer in one device with a digital display for easy adjustment of the setpoint, reset point, and the switching function. The setpoint is the pressure value where the switch activates and the reset point is the value at which the switch deactivates when the pressure decreases. The setpoint can be adjusted between 0 and 160 bar (0 and 2321 psi). The maximum overpressure is 320 bar (4641 psi). The accuracy of the analog signal is ≤ ±1 % of span. This includes non-linearity, hysteresis, zero offset and end value deviation (corresponds to measured error per IEC 61298-2). The switching capacity for this pressure switch is 250 mA @ 1 V DC, the power supply is 15 – 35 V DC and the output signal is two switching outputs (PNP). It can be connected to an electrical network with a 4-pin M12 connector. This pressure switch is made in a diaphragm design with a stainless steel body. It is suitable for various media, such as compressed air, hydraulic oil and in a temperature range from -20 to 80°C (from -4 to 176°F). The connection port has a size of G 1/4 inch with male threads. The pressure switch has an IP67 rating.
Pros:
- Long working life and low signal drift
- Works as a switch and transducer
- It has a digital display to adjust the settings
- The IO-Link communication standard allows a fast integration into modern automation systems.
Cons:
- Electronic pressure switches need a power supply
PSD-30 series
Tameson offers a wide range of mechanical and electronic pressure switches. The mechanical pressure switches are available with three different types of contacts: normally open (NO), normally closed (NC) and changeover contacts. The setting pressure is typically adjusted with a hex key or turning knob. The electronic pressure switches have a digital display to set up the switching function. Electronic switches often combine the function of a pressure transducer with a 0-10 V, 4-20 mA or digital output signal. The setting pressure range for these pressure switches is from -1 to 600 bar (from -14 to 8702 psi) and overpressure safety of up to 600 bar (8702 psi) can be attained. Hysteresis is the difference between the switch point and the reset point. Mechanical switches have a hysteresis in the range of 10-30% while electronic switches are often configurable. Choose from a wide range of switch capacities. Please note that maximum load is dependent on voltage and different loads are allowed for AC or DC voltage. Electronic pressure switches require power supply to function. Choose from brass, steel or stainless steel options with various sealing materials to be compatible with your medium and temperatures. Check our chemical resistance table when in doubt. Furthermore, choose from a wide range of options such as mounting standards, electrical connections, ATEX approvals and more.
