Description
This 4bar pressure switch is part of the XML range, an offer of electromechanical pressure and vacuum switches. These switches have an adjustable differential and are designed for regulation between two thresholds. The function of pressure switches is the control or regulation of pressure levels in hydraulic systems. They transform the pressure change into a digital electrical signal when the preset switching points are reached. This pressure switch has a setting scale overpressure 30bar (435psi) and an adjustable range of switching point, or rising pressure, from 0.25bar to 4mbar (3.62psi to 58psi). Thanks to the electromechanical technology, this product is reliable and simple to use. It incorporates one C/O single-pole contact, snap action. It has a diaphragm pressure actuator. This pressure switch features a zinc alloy case, a G 1/4 female fluid connector and one entry tapped for Pg 13 cable gland. It is suitable for controlling hydraulic oils, fresh water and air up to +160°C. It complies with UL, CSA, EAC, CCC, BV, LROS certifications and with CE, IEC/EN 60947-5-1, UL 508, CSA C22-2 no. 14 standards. Dedicated accessories, to be ordered separatly, are available to facilitate the setting or ptotect the switch. Knurled adjustment knob, fixing plate, lead sealable protective cover, sealing gaskets, etc. This switch operates in all positions. The XML range brings high level of reliability and quality, long life duration, and a worldwide availability.
