SOR now has an enhanced version of their popular pressure transmitter, model 805PT. The new 805QS provides a continuous output signal corresponding to pressure, but also incorporates a failsafe adjustable pressure switch into the same device. The switch can be configured in the factory or field to operate in one of three ways:
  • Switch is closed when pressure is above a low setpoint and below a high setpoint. This is referred to as a "window" setting.
  • Switch is closed when pressure is above a setpoint.
  • Switch is closed when pressure is below a setpoint.
In all variants, the switch will open on loss of power. The loop powered unit is designed so that the switch and output signal operate independently. Other features include a five millisecond response time, full range temperature compensation, and global certifications.
