Dual and triple switch versions provide multi-output for
alarm and shutdown, pre-alarm and alarm, high/low limit or level staging
functions.
Widely used throughout the process industries, the 400
Series provides threshold protection and control for many critical functions.
Typical installations are found in industrial gas production, energy generation
including pumps, turbines and compressors, pulp and paper, and water and
wastewater treatment.
- 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 REPEATABILITY: Temperature models: ± 2% of full
scale range 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 SPDT switches, may be
separated up to 100% 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; 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 model
- 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 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: Differential pressure
indication available J400K, J402K models 147-S157B; PRESSURE 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
