Pneumatic High and Low Temperature Detection Thermostats
134
The 134 High and Low Temperature Detection Pneumatic Thermostats automatically “lockout” at setpoint and require manual reset.
• Snap-acting pneumatic switch
• Sight-set calibrated setpoint scale
• No leakage of air prior to reset of switch
• Easily adjustable settings
• Normally closed air valve; bleeds to less than 2 psi (14 kPa) when supplied through a restrictor
• Barb fitting for push-on connection of 1/4 (6 mm) OD polyethylene tubing
• Holds dead-ended line to approximately 22 psi (152 kPa) air pressure
