Dwyer 3002 Series 3000 Photohelic Pressure Switch/ Gage, Range: 0.0 - 2.0 Inches Of Water

Manufacturer: Dwyer Instruments Brand: Dwyer Model: A3000-150CM

Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Photohelic switch/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 set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points 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) WC up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar).

Designed to be the most adaptable switch on the market, the 69J offers the user the flexibility to build the pressure switch around the compressor-not the other way around. The unloader can be mounted on the front or either side, and can be rotated to any of eight different positions allowing for quicker assembly and shorter tubing. Bottom cable entry is also available with unique built-in clamping strain relief for even quicker assembly. With thousands of variations right off the production line, the 69J provides maximum flexibility at minimum cost.

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.
