INSTALLATION INSTRUCTIONS
AND USER MANUAL

Product description and intended use

Sensor types T-SIL-PATCH (thermocouple, TC) and W-SIL-PATCH (resistance, RTD) are silicone patch sensors with cable for surface temperature measurement.
Sensors are intended for quick and easy installation in various surface measurement applications. The sensor element is covered with a flexible silicone patch which can be attached in many ways to the surface to be measured. As an option, the silicone patch can be delivered with 2-sided adhesive aluminum foil tape with good thermal conductivity on the measuring surface.
Elements can be TC or RTD elements, standard versions are K-type thermocouple (for T-SIL-PATCH) and 4wire Pt100 (for W-SIL-PATCH). Wire and cable length and materials can be chosen.
Tailored versions are produced on request.
EPIC® SENSORS temperature sensors are measuring devices intended for professional use. They should be mounted by a professionally capable installer who understands the installation’s surroundings. The worker should understand mechanical and electrical needs and safety instructions for the object installation. Suitable safety gear for each installation task must be used.

Temperatures, measuring

Allowed measuring temperature range for sensor tip (silicone sensor head, patch) is:

• With Pt100 ………….. -40…+180 °C
• With TC ……………… -40…+180 °C

NOTE! Model 40x15x3: The allowed maximum temperature for heat shrink tubing on the sensor end is +125 °C. Please see the Dimensional drawing.

Temperatures, ambient

Allowed maximum ambient temperature for wires or cable, according to cable type, is:

• SIL = silicone, max. +180 °C
• FEP = fluoropolymer, max. +205 °C
• GGD = glass silk cable/metal braid jacket, max. +350 °C
• PDF = FEP wire insulation/braid shield/FEP jacket, max. +205 °C
• SDS = silicone wire insulation/braid shield/silicone jacket, only available as 2 wire cable, max. +180 °C
• TDT = fluoropolymer wire insulation/braid shield/ fluoropolymer jacket, max. +205 °C
• FDS = FEP wire insulation/braid shield/silicone jacket, max. +180 °C
• FS = FEP wire insulation/silicone jacket, max. +180 °C
• CON = no cable, individual single wires, FEP wire insulation, max. +205 °C

NOTE! Model 40x15x3: The allowed maximum temperature for heat shrink tubing on the sensor end is +125 °C. Please see the Dimensional drawing.
Make sure the process temperature is not too much for the cable or heat shrink tube.

Installation instructions

Before any installation, make sure the target process/machinery and site are safe to work!
Make sure the cable type matches the temperature and chemical requirements of the site.
Installation phases:

• Apply the silicone patch on a surface to the measured.
• Use a pipe clamp or cable tie or similar, to fix the patch closely to the surface.
• Or apply the patch with 2-sided adhesive aluminum foil (delivery option)
• Or, depending on the surface material, the patch can be screwed or nailed down through the patch’s outer ends.
• Or weld a special fixing part on the measured surface, then insert the sensor patch in.
• Make sure there is no excess bending force loading the cable.
• Mount extra strain relief, e.g. cable tie, for cable, if necessary.

The image below: this example shows a sensor installed with a pipe clamp, and with a welded fixing accessory.

Pt100; connection wiring

The image below: These are the connection colors of Pt100 resistor connections, according to standard EN 60751.

Other connections on request.

Pt100; measuring current

The highest allowed measuring current for Pt100 measuring resistors depends on resistor type and brand.
Normally the recommended maximum values are:

• Pt100 ……. 1 mA
• Pt500 ……. 0,5 mA
• Pt1000 ……. 0,3 mA.

Do not use a higher measuring current. It will lead to false measurement values and might even destroy the resistor.

TC; connection wiring

The image below: These are the connection colors of TC types J, K, and N.

Other types on request.

TC; non-grounded or grounded types

Normally the thermocouple sensors are non-grounded, which means the protective tube / MI cable sheath is not connected to the Thermo material hot junction, where two materials are welded together.
In special applications also grounded types are used.
NOTE! Non-grounded and grounded sensors cannot be connected to the same circuits, make sure you are using the right type.

The type label of standard versions

Each sensor has a type label attached to it. It is a moisture and wear-proof industrial-grade sticker, with black text on a white label. This label has printed information as presented below.
