INSTALLATION INSTRUCTIONS
AND USER MANUAL

Product description and intended use

Sensor types T-106 (thermocouple, TC) and W-106 (resistance, RTD) are temperature sensor probes for food industry.
Sensors are intended for measuring food materials. A sharp tip probe is manually inserted into material. Sensor element protection tube material is acid proof steel, and cable type / length can be chosen according to customer needs.
Measuring elements are rigid, non-bendable versions. Elements can be TC or RTD elements, standard versions are K-type thermocouple (for T-106) and 4-wire Pt100 (for W-106). Tailored versions are produced on request.
EPIC® SENSORS temperature sensors are measuring devices intended for professional use. They should be mounted by professionally capable installer who understands the installations surroundings. The worker should understand mechanical and electrical needs and safety instructions of the object installation. Suitable safety gear for each installation task must be used.

Temperatures, measuring

Allowed measuring temperature range for sensor tip is:

• With Pt100 -200…+300 °C, depending on materials
• With TC -200…+300 °C, depending on materials

NOTE! The maximum temperature for plastic handle cover material is +110 °C.

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
• FDF = 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

NOTE! The maximum temperature for plastic handle cover material is +110 °C.
Make sure the process temperature is not too much for the cable or plastic handle.

Materials

These are the standard materials of components for the sensor types T-106 / W-106.

Other materials can be used on request.

Installation instructions and example

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:

• First, connect the wires to measuring instrument.
• Insert the sensor tip into the material to the measured.
• Make sure there is no excess bending force loading the cable.
• Mount extra strain relief, e.g. cable tie, for cable, if necessary.

Installation of accessories

Connectors:
For TC versions there are thermocouple connectors available, as components.
These connectors have male or female contacts, made of alloys suitable for a certain thermocouple type. The connector body is also colored depending on the TC type, e.g. type K connector body is green, because type K cable sheath is green, according to standard IEC 60584.
The maximum temperature for these connectors is +200 °C, if not specified otherwise.
There are two sizes of TC connectors: standard (STD) and miniature (MINI).
TC connectors available are: (Other types are quoted upon request.)

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:

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

TC; connection wiring

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 same circuits, make sure you are using the right type.
Image below: Non-grounded and grounded structures in comparison.

Non-grounded TC		Thermo material hot junction and protective tube / MI cable sheath are galvanically isolated with each other.
Grounded TC		Thermo material hot junction has galvanic connection with protective tube / MI cable sheath.

Type label of standard versions

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

Serial number information

Serial number S/N is always printed on type label in the following form: yymmdd-xxxxxxx-x:
▪ yymmdd…………….. production date, e.g. “210131” = 31.1.2021
▪ -xxxxxxx………….. production order, e.g. “1234567”
▪ -x………………sequential ID number within this production order, e.g. “1”
