specifications
Storage temperature -65 to 160°F (-54 to 71°C)
Ambient TEMPERATURE -40 to 160°F (-40 to 71°C); set point typically shifts less than 1% of range for
limits a 50°F (28°C) ambient temperature change
Set point Temperature models: ± 2% of full scale range
repeatability Pressure: models 126-376, 520-535, 540-547, 570-572, S126B-S164B: ± 2% of
full scale range; models 440-457, 550-559: ± 1% of full scale range; models
610-614: ± 3% of full scale range
Shock Set point repeats after 15 G, 10 millisecond duration
Vibration Set point repeats after 2.5 G, 5-500 Hz
Enclosure Die cast aluminum, epoxy powder coated, gasketed, captive cover screws
Enclosure Designed to meet enclosure type 4X requirements
classification
Switch output One, two or three SPDT switches, may be separated up to * of range except
models 521-524, 531-534: 50%; models 520, 525, 530, 535, 570-572: 30%;
switches may be wired “normally open” or “normally closed”
Electrical rating 15 A 125/250/480 VAC resistive. Electrical switches have limited DC
capabilities. Consult factory for additional information.
Weight Approx. 3 to 7.5 lbs.; varies with model
Electrical One 3/4” NPT and two 7/8” diameter knockouts connection
Pressure All models 1/4” NPT (female) except models S126B-S164B, 520-535: 1/2” NPT
connection (female); models 540-547: 1/8" NPT (female)

Temperature ‘E’ types use the same assemblies as ‘F’ types, however, range spans are limited assembly due to use of reference dials
Bulb and capillary: 6 feet 304 stainless steel
Immersion stem: models 120 &121: nickel-plated brass; optional 316L stainless steel available
Fill Temperature Models: Model 1BS: solvent filled; models 2-8: non-toxic oil filled Temperature Type F typically 1% and type E, B & C typically 2% of range under laboratory deadband conditions (70°F ambient circulating bath at rate of 1/2°F per minute change)
Differential Differential pressure indication available J400K, J402K models 147-S157B;
pressure indicator accuracy approximately 1-1⁄2% mid 50% of range, 3% at ends; window is (option M210) plexiglass and gasketed; indicator may be field adjusted for approximately ±1% accuracy at any set point within range
