Tecmark Corporation Pressure Switch TBS 3000

Series TBS3000 fixed set point pressure switches and VTBS3000 f ixed set point vacuum 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. Fixed set point style switches are widely used where basic on/off switching is required. The nonadjustable fixed set point feature provides excellent tamper-proof protection. Several standard fixed set points are available ranging from ¾ PSI to 2 ½ PSI (5.17kPa to 17.24 kPa) on positive pressure and -0.8 PSI to -5 PSI (-5.51kPa to -34.47kPa) on negative pressure. Series TBS3000 and VTBS3000 switches provide control stability through wide variable temperature and humidity conditions and assure uninterrupted service under extreme shock and vibration. As with all Tecmark® products, these switches provide superior performance and 100,000 cycle life under full mechanical, electrical and thermal loads.
