TEC Controller Hardware Configuration

Our TEC controllers need to be ordered with a hardware configuration chosen by the customer. The TEC controllers are configured and tested internally before shipping. This article is intended to clarify questions about hardware configuration.

Order Help / Options Assistant

The following hardware configurations are available in addition to the models:

A few examples:

  • TEC-1091-PT100-SCREW
    Model: TEC-1091 Sensor Type: PT100 Terminal Configuration: SCREW
  • TEC-1161-4A-PT1000-PIN
    Model: TEC-1161-4A Sensor Type: PT1000 Terminal Configuration: PIN
  • TEC-1122-SV-NTC
    Model: TEC-1122-SV Sensor Typ: NTC Terminal Configuration

Sensor Options: ?s?

The following sensor types are available for our TEC controllers:

Sensor TypeTemperature Measurement Range
PT100 -100 to +200 °C (See TEC Controller datasheets for exact values)
PT1000 -100 to +200 °C (See TEC Controller datasheets for exact values)
NTC -55 to +131 °C assuming an NTC thermistor 10k@25 °C (B approx. 3900) is used
VIN1

The following sensor type is only available for our TEC-1091, TEC-1161, TEC-1162, TEC-1163, TEC-1166, TEC-1167:

Sensor TypeTemperature Measurement Range
VIN2

Explanation NTC

The NTC hardware configuration allows the connected thermistor to be measured up to a maximum of 1M ohms. If the connected thermistor is bigger than 1M Ohm, 1M Ohm is measured. The NTC configuration corresponds to the previous NTC1M version.

If you need an older version (NTC18K, NTC39K or NTC56K), please write it in the comment of your order or contact us: contact@meerstetter.ch.

Explanation Thermocouple

To use our TEC Controller with thermocouples type K, you need a TCI-1181 in addition to the TEC Controller with a VIN1 object sensor type configuration. The TCI-1181 is a very small thermocouple readout circuit that amplifies and linearizes the thermocouple output.

The TCI-1181 has the following hardware configuration:

  1. Thermocouple temperature range type: K or KH

  2. ThermocoupleTemperature Measurement Range
    Typ K -195 to +320 °C for TEC-1089, TEC-1090,  TEC-1091 HW v1.8, TEC-1122, TEC-1123
    -195 to +400 °C for TEC-1091 from HW v3.15, TEC-1092, TEC-1061-xx, TEC-1162, TEC-1163, TEC-1166, TEC-1167
    Typ KH (high temperature range) 5 to +540 °C for TEC-1089, TEC-1090,  TEC-1091 HW v1.8, TEC-1122, TEC-1123
    5 to +760 °C for TEC-1091 from HW v3.15, TEC-1092, TEC-1061-xx, TEC-1162, TEC-1163, TEC-1166, TEC-1167

  3. Thermocouple Connector (X1): NC (solder eye only) or MC (standard mini socket Farnell S/N 2810611)
  4. Board Connector (X4): NC (solder eye only) or SCREW (see below)

Software Configuration

The parameters of the thermocouple sensor must be entered in the TEC Controller Software so the TEC Controller can calculate the temperature. You only need to enter the voltage at a given temperature (Reference Voltage and Reference Temp) and the Temperature Slope, the rest is calculated automatically.

In the TEC Service Software (FW ≤ v5.10), enter the values in the "CHx Object Voltage to Temperature Conversion" within the "Advanced" -> Temperature Conversion" tab.

In the TEC Configuration Software (FW ≥ v6.00), click on the appropriate "HR Input x" box and enter the values in the "Temperature Conversion" area.

The following terminal options are available and can only be specified for TEC-1091 and TEC-1161-xx, likewise in a different constellation for TEC-1162, TEC-1163, TEC-1166 and TEC-1167:
