The TH-22 Series thermistor probes are constructed
with the 55000 Series glass encapsulated
thermistor elements which provide excellent
stability and accuracy. The connector design includes
an LCP insert with nickel plated copper pins for high
temperature applications, 200°C (392°F).
With a maximum continuous temperature rating of
-80 to 200°C (-112 to 392°F), and intermittent
operation to 250°C (482°F), these thermistor
sensors can be used in applications previously
out of reach of epoxy coated thermistor sensors.
The probes can be ordered in any length but we
highly recommend a minimum immersion depth
of 1.5". Short probes run the risk of error due
to stem conduction effects.
Specifications Temperature Range: -50 to 200°C (-58 to 392°F) Thermistor Sensor: Refer to Table 1 on next page Operating Current: 12 micro-amps Insulation Resistance: 100 MΩ minimum at 100 Vdc at ambient temperature Response Time: Approximately 7 seconds (50%), 8 seconds (63.2%), 14 seconds (90%) in water flowing at 0.91 m (3') per second External Materials: 316L stainless steel sheath and housing except connector insert IP Rating: IP67 with mating connector installed
† All amounts shown in EUR, GBP, or USD Note: For lengths other than 6", change “-0600” in model number to required length and add additional cost per inch greater than 6", (example: 9" = 0900, 41/2" = 0450). For 1/8" probe diameters, change “-1/4” in model number to “-1/8”, no additional cost. For 3K, 5K or 10K O thermistor elements change “-2252” to desired resistance. For dual element 1/4" or 6 mm diameter versions, add “-DUAL” to the end of the model number (not available in 1/8" or 3 mm diameter probes), for an additional cost.
