Pneumatic Bulb Thermostats
General Instructions
For proportional temperature control of pneumatic valves and actuators to maintain discharge temperature of reheat systems and sampling chamber or return air temperature of terminal units and as a proportional low limit thermostat.
GENERAL INFORMATION
Proportional control type of pneumatic instrument, using balanced lever system actuated by a liquid-filled thermal copper element with a 3’ (914 mm) capillary.
Maximum Safe Air Pressure: 30 psig (207 kPa). Maximum Sale Case Temperature: 140°F (60°C).
Mounting: Directly by means of top mounting holes or with a right angle mounting bracket included with thermostat.
Air Connections: Post with barb for 1/4" O.D. plastic tubing.
Air Consumption for Sizing Air Compressor: .016 scfm (8 ml/s) @ 15 psig (103 kPa), .024 scfm (11 ml/s) @ 20 psig (138 kPa).
Air Capacity for Sizing Air Mains: 36 scim (10 ml/s) @ 15 psig (103 kPa), 50 scim (14 ml/s) @ 20 psig (138 kPa). Dimensions: 4-5/8" (117 mm) high x 2-1/8" (54 mm) wide x 1-5/8" (41 mm) deep.

aDirect Acting (DA) - Increase output pressure on temp. rise. Reverse Acting (RA) - Decrease output pressure on temp. rise.
bField changeable to reverse acting.
cAT 20 psi (138 kPa) unit can bleed down a branch line from a controlling thermostat. At 15 psi (103 kPa) unit is inoperative, i.e. passes controlling thermostat signal.
