Pneumatic Transmitters

Temperature Transmitter Replacement Kits

Retroline Temperature Transmitters are direct acting, one-pipe instruments which sense temperature and transmit a proportional pneumatic signal to the remotely located receiver gauge and/or receiver controller.

  • Temperature ranges exactly match replaced product
  • Room transmitter comes complete with mounting hardware and cover
  • Remote sensing bulb size and capillary length same as replaced product
  • Installation instruction provided

Unit Mounted Thermostat Replacement Kits

The unit mounted thermostat is a remote bulb, gradual acting instrument designed to control the temperature within an occupied space by positioning pneumatic devices. It is factory calibrated to competitor’s changeover pressures, making replacement easy.

  • Direct replacement of competitor’s models
  • Factory calibrated changeover supply pressures
  • Adjustable sensitivity
  • Liquid filled thermal system
  • Mounting bracket provided

Pneumatic Calibration Card

Substitution of pneumatic controls is relatively simple. One problem, however, is that control manufacturers cannot agree on terminology because they don’t want you to change their part to another brand. This chart can be used to eliminate that confusion, giving you the flexibility to substitute whatever brand you prefer. This way you can select the best product for the application, no matter who makes it.
