Dwyer Series 43000 Capsu-Photohelic® Pressure
Switch/Gage |
| Lo-Limit and Hi-Limit Control,
Aluminum or Brass Case Available |
| |
Capsu-Photohelic® Switch/Gages function
as versatile, highly repeatable pressure switches combined with
a precise pressure gage employing the time-proven Magnehelic® design.
The Capsu-Photohelic® employs an encapsulated sensing element
for use with both liquids and gases at pressures to 500 psig
(34 bar). Optional cast brass case is available for water or
water based liquids. 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 pumps, etc. Dimensional
Information |
| |
| Set points are instantly adjusted
with front knobs. |
