TEMPERATURE PROBES & THERMOCOUPLES
Temperature/ Thermocouple Probes for Zones 2 & 3
TA, TAS:
For Zone 2 use; low temperature, gives
fast response; good in steep temperature
gradients. Also used in Zones 4, 5, and 6
for inexpensive
construction.
Standard diameters: 1/16", 1/8", 1/4"
TB, TBS:
For Zone 2 use; requires deeper immersion in gas to eliminate conduction. Good protection for thermocouples, basis
of completely pressure
tight assembly. Good in liquids. Also used in Zones 4, 5, and 6 for inexpensive construction and as
elements in multiple shielded
probes.
Standard diameters: 1/8", 1/4"
TU, TUS:
Same as TB, TBS, except junction is
grounded to tip of stem for fast
temperature response. TUS is made with
Mineral insulated cable
for bending<
installation.
Standard diameters: 1/16", 1/8", 1/4"
TC, TCS:
For Zone 3 use; Common in all types of compressors for efficiency measurements.
Typical Example: TBS-6-K-36-C-1-F
| TBS: | Type TBS | ||||||
| 6: | a = 6" - Probe length | ||||||
| K: | Type of thermocouple wire: K = Chromel - Alumel Thermocouple J = Iron - Constantan T = Copper - Constantan E = Chromel - Constantan |
||||||
| 36: | g = 36" - Lead wire length. Plugs or Jack terminations are available. | ||||||
| C: | d = 1/8" - Probe diameter
|
||||||
| 1: | b = 1" - Reinforcement tubing length | ||||||
| F: | m
= 1/4" - Reinforcement tubing diameter
