The 1309007-044 Thermistor Sensor Is Used with The Ranco Etc Family Of Electronic Temperature Controls and Supports A Temperature Range Of -30 °F To 220 °F.
The Sensor Can Be Used For Air, Duct or Spot Sensing. It Can Also Be Used In Bulb Wells For Immersion Applications.
Multiple Sensors Can Be Wired In A Series/Parallel Arrangement For Sensing Average Temperature. For Each Number Of Sensors Wired In Series, An Equal Number Must Be Wired In Parallel. (Wiring Diagram For Averaging Is Shown In Figure 1.)
For Space Sensing, Mount The Sensor Where It Will Be Unaffected By Heat/Cool Discharge or Radiated Heat Sources. Spot Sensing Requires The Sensor To Be In Good Contact with The Surface Being Sensed.
The Sensor Can Be Inserted In A Bulb Well For Immersion Sensing. 1309007-044 Sensors Are Designed For Use Only with Ranco Type Etc Temperature Regulating Controls.
Where A Control or Sensor Failure Could Result In Personal Injury and/or Loss Of Property, It Is The Responsibility Of The Installer To Add Devices (Safety, Limit Controls) or Systems (Alarm, Supervisory Systems) That Protect Against, or Warn Of Failure.
Field Repairs, Field Calibrating or Repairs To The Etc Control Must Not Be Attempted. Sensors and Replacement Controls Are Available Through Local Wholesalers. Òsensor Resistance Decreases with Temperature Increase. Òdamaged Sensor Can Be Replaced By Splicing New Sensor To The Cable. Òsensor Is Not Polarity Sensitive.
