Series 3000 pressure
switches convert a pressure signal to an electrical
output. In response to a change in pressure, movement of an
elastomeric diaphragm opens or closes an electrical circuit
based on a predetermined pressure set point. The Series 3000
features cost effective, snap-acting electrical switches and
field adjustable set points with a visual scale for easy set
point selection. Pressure ranges as low as 2" Water Column
(W.C.)* up to 100 PSI are available. Series 3000 switches assure
control stability through wide and variable temperature and
humidity conditions and assure uninterrupted service under
extreme shock and vibration. As with all Tecmark® products,
series 3000 switches provide superior performance and 100,000
cycle life under full mechanical, electrical and thermal loads.
Series 3900 pressure switches are widely used in pilot duty applications and incorporate field adjustable set points and internal switch contacts. These switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. The Series 3900 feature a compact size and a cost effective, combination terminal design which allows electrical connection with either 1/4" quick connect or #8 screw terminals. Pressure ranges as low as 6" Water Column (W.C.)* up to 5 PSI are available (1.5 kPa to 34.5 kPa). Series 3900 switches assure control stability through wide temperature and humidity conditions. As with all Tecmark® products, Series 3900 switches provide superior performance and uninterrupted service, even under extreme shock and vibration.
