2.2. Temperature switch mounting
Observe the environmental and fluid-related conditions corresponding to the characteristics of the instruments.
Never exceed the maximum temperature of the instrument indicated on the label on the side of the housing.
A capillary introduced into the liquid can be of any length.
2.2.1. Direct probe device (Type B) :
Secure the instrument via its fitting (on G 3/8" thread as standard, other on request).
Completely immerse the probe.
2.2.2. Ambient monitoring instrument (Type BA) :
The instrument must be installed in a well ventilated location, away from heat sources or refrigerant devices. It must
not be subjected to sudden temperature changes.
For monitoring in inhabited buildings, install the temperature switch 1.50 m above the floor and far from
external walls.
2.2.3. Remote probe device (Type C) :
Do not constrain the capillary. It must remain flexible to transmit the signal.
Roll the capillary with a diameter of at least 80 mm.
NOTE: In certain cases, the size of the bulb and the length of the capillary can be specified in the order.
a. Monitoring fluids
Completely immerse the probe.
Use an appropriate type GBX or GCX immersion sleeve immersed perpendicular to the flow, or use
a PC(X)**(B) capillary cable gland according to the existing process fitting type.
b. Monitoring surfaces
Carefully clean the contact surface and the probe.
Secure the probe using a metal (preferably cuprous) collar, covering the
length of the probe.
Add thermal insulation on top.
Take care to observe the probe orientation (see Chapter III - 4..1.2)
Thermal insulation
Copper alloy flange
2.2.4. Accessories :
Capillary cable gland kit:
If the capillary outlet must be sealed, use our special PC(X) type cable gland.
