Simplified programming and the ability to be retrofitted in to any existing temperature head are two of the benefits offered by ABB's new TH01 head-mounted temperature transmitters.

Simplified programming and the ability to be retrofitted in to any existing temperature head are two of the benefits offered by ABB's new TH01 head-mounted temperature transmitters.

Available in a standard DIN format and featuring ABB's new programming method, TH01 and TH01-Ex transmitters offer what is claimed to be convenient and cost effective temperature measurement for use in standard, intrinsically safe and ATEX applications.

Designed for use across a range of industries, TH01 temperature transmitters feature electrical isolation and meet NAMUR standards for use in chemical and pharmaceutical applications.

The TH01-Ex explosion-proof version is approved for use in ATEX zones 1 and 2.

All transmitters in the range are colour coded, making it easy to identify which model to use for a particular installation, said the company.

Setting up the transmitters is made easy by ABB's Easy Configuration (Eco) Message method, claimed the company.

Using that method, users can set up TH01 transmitters with the full range of transmitter functions with any software tools or handheld terminals using standard HART universal and generic commands without the need for device-specific drivers, which commonly restrict the level of functions, added ABB.

By eliminating the complexity associated with programming traditional transmitters, the Eco Message method allows users to typically save up to 10 minutes per transmitter, particularly suitable for large sites where many units may be installed.

Localised programming and reprogramming is also possible using ABB's Prometer interface display.

The Prometer features push buttons that the operator can use to configure parameters in the field.

Although the TH01 can be programmed digitally, it can also be used in the same way as an analogue device, enabling it to receive analogue inputs.

TH01 transmitters can receive inputs from all resistance thermometers, thermocouples and remote resistance sensors.

The resistance thermometer version is suitable for all PT100ohm resistance applications between -200 degrees C to +850 degrees C, with a minimum span of 15 degrees C.

The transmitter measures temperature by converting the output from a resistance thermometer in to a 4-20mA signal proportionally, said the company.

The thermocouple version accepts all the standard element types (B, E, J, K, L, N, R, S, T, U).

The millivolt output from the connected thermocouple is converted in to both a 4-20mA linearised and a galvanic isolated signal.

The TH01 is suitable for temperatures between -270 degrees C and +1,820 degrees C, with a minimum span equivalent to two millivolts.

All devices in the TH01 range are fully EMC compliant.

The devices are protected against the effects of radiated fields with strengths of 80mhz to 1Ghz and 10 volts per metre.

The range comprises the TH01 and TH01-Ex models for use in head-mounted assemblies and the TH101 and TH101-Ex rail devices, each with the option of single or dual-channel versions.

A standard three-year warranty period applies to each model.
