The SERIES EWDP Wireless Communication Adjustable Differential Pressure Switch uses EnOcean® wireless technology to monitor pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches of water column and pascals allows changes to the pressure set point to be made without a pressure gage. The battery-powered switch is equipped with radio module for frequencies of 902 MHz or 868 MHz which sends a signal wirelessly to a Series USB-300 receiver at each change of status. The silicone diaphragm makes this series ideal for use with air and other non-combustible gases. The EWDP is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa). The compact size, adjustment knob, and wireless capabilities make the EWDP the perfect choice for HVAC applications in temporary installations or retrofits of existing buildings.

The Photohelic® gage measures and controls positive, negative or Differential Pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust setpoint indicators are controlled by knobs located on the gage face. Individual setpoint deadband is one pointer width - less than 1% of full scale. Setpoints can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25" (0-6 mm) w.c. up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar). PHOTOHELIC SENSING - HOW IT WORKS In typical applications, these Dwyer switch/gages control between high and low pressure set points. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Dead band between make and break is 1% of full scale or less. RELAY-TRANSFORMER FEATURES A plastic housing protects all electronic components. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards (for the Series A3000 only). STANDARD MODEL Two phototransistor-actuated circuits and two DPDT relays permit both high and low alarms or limit controls. Relays are de-energized when gage pointer is to the left of respective set points; relays are energized as pointer passes to the right of set points. Loss of electrical power or loss of pressure provide "fail safe" protection.
