On the Series 1620 Single and Dual Pressure Switch, our old faithful switch design is still best where highest precision combined with diaphragm sealed leak proof construction and mounting simplicity are required. Model 1626 and 1627 differential pressure switches are identical in design and construction except that Model 1626 has a single electric switch and Model 1627 has dual electric switches. Model 1627 can therefore provide dual control when required. It can be set to open or close two independent electrical circuits, each preset for its own actuation pressure. Both units have diaphragm sealed motion take outs providing maximum protection against leakage.

The Series MDPC Mini Digital Pressure Controller is a slim, gas pressure sensor that is small in size and light in weight. This pressure controller supports many installation methods and features high measurement accuracy. This small controller yields excellent stability, high shock and vibration resistance. The MDPC also provides good over-load capacity and heat resistance. It can be utilized in many industries such as: high-tech electronics, general processing, food packaging and automatic assembly. The MDPC features 6 user selectable pressure units and a large, LED 3-color display with selectable color options that allow for easy reading. Changing units is simple, and by using the included unit stickers, the pressure unit displayed becomes very clear. The fast parameter copy function makes copying parameters to other MDPC pressure controllers effortless. The key lock mode also prevents any unnecessary changes to the parameters, which can have an effect on the operation. Another characteristic of this multi-talented pressure controller is its ability to detect both positive and negative pressure. The MDPC is available in NPN, PNP, analog voltage or current output control modes.

Differential pressure switch for monitoring overpressure, differential pressure, or underpressure of air and non-flammable, non-aggressive gases. Can be used as a fume cupboard or fan monitor or flow monitor to protect electrical heating coils, as a filter monitor, air pressure deficiency protection, or limit controller. Note: Once the differential pressure switch has switched a voltage > 24 V and a current > 0.1 A, the gold layer on the contacts is burnt away. After that, the differential pressure switch can only be operated with this or a higher power. Note: The hose set JZ-06 / 1 is not included in the scope of delivery and must be ordered separately.

Explosion-proof Series H3 Explosion-Proof Differential Pressure Switch, heavy duty, industrial unit has a unique new design which provides sensitivity to differential pressures as low as 10 inches of water (254 mm w.c.), yet handles total pressure of 1500 psi (103 bar). Unlike common differential pressure switches that use a piston-type motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a setpoint shift. Unit yields deadbands approximately 5% of range, with zero setpoint shift due to variation in working pressures. Friction is minimized and repeatability increased by allowing range spring to act directly on diaphragm plate. Rolling diaphragm design maintains constant effective area to further reduce friction. Diaphragm is allowed to “seat”, allowing application of full rated pressure, up to 1500 psi (103 bar), on either high or low pressure port, without damage. Special over-travel feature prevents overtightening of range adjust screw.
