AMBIENT TEMPERATURE LIMITS

-40 to 160°F (-40 to 71°C); set point typically shifts less than 1% of range FORECAST4 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 CLASSIFICATION

Designed to meet enclosure type 4X requirements

SWITCH OUTPUT

One, two or three single-pole double-throw (SPDT) outputs; 100% adjustable within the adjustment range; 521-524, 531-534: 50%; 520, 525, 530, 535, 570-572: 30%; Switches can be wired as "normally open" or "normally closed"

ELECTRICAL RATING

15 A 125/250/480 VAC resistive. Electrical switches have limited DC capabilities; at 24-30 VDC, 2A resistive and 1A inductive; at 125 VDC, 0.5A resistive and 0.03A inductive. Consult factory for additional information.

WEIGHT

Approx. 3 to 7.5 lbs.; varies with mode

ELECTRICAL CONNECTION

One 3/4” NPT and two 7/8” diameter knockouts

PRESSURE CONNECTION

All models 1/4” NPT (female) except models S126B-S164B, 520-535: 1/2” NPT (female); models 540-547: 1/8" NPT (female)

TEMPERATURE ASSEMBLY

‘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 v
stainless steel available

FILL

Temperature Models: Non-toxic oil filled

TEMPERATURE DEADBAND

Type F typically 1% and type E, B & C typically 2% of range under laboratory
conditions (70°F ambient circulating bath at rate of 1/2°F per minute change)

DIFFERENTIAL

Applicable to Model 147-S157B for J400K, J402K; Approximate accuracy is 1.5% at 50% of range and 3% at both ends; Indicator window is made of flexible glass; Indicator can be adjusted on site with an accuracy of 1% of the set point range.
