Dwyer Instruments 43000-8CM Capsu-Photohelic Switch/Gauge

Overview

The Capsu-Photohelic switch/gauge provides low- and high-limit control with two phototransistor-actuated DPDT relays. Set points are adjusted with knobs on the gauge face, and each set point deadband is one pointer width, less than 1% of full scale. Set points can be interlocked to provide variable deadband control, which is ideal for pump control.

The -8CM model covers 0-8 cm w.c. Water or water-based liquids require the optional cast brass case. Zero and range adjustments are made from outside the gauge, so no disassembly is needed in normal service.

Features

  • Pressure switch and precise gauge in one unit
  • 0-8 cm w.c. range
  • Two phototransistor-actuated DPDT relays
  • Adjustable set point knobs on the gauge face
  • Deadband less than 1% of full scale
  • Zero and range adjustments accessible outside the gauge
  • Aluminum case; optional cast brass case for water-based liquids

Applications

  • Pump control and pumping systems
  • Waste water and compatible liquid or gas applications
  • Low- and high-limit pressure alarm and control
