The TIF series field temperature transmitters, consisting of a rugged field housing, model T32 temperature transmitter and a model DIH display, have been designed for general use in process engineering. They offer high accuracy, galvanic isolation and excellent protection against electromagnetic influences (EMI). Via HART® protocol, the TIFxx is configurable (interoperable) with a variety of open configuration tools. In addition to the different sensor types, e.g. sensors in accordance with DIN EN 60751, JIS C1606, DIN 43760, IEC 60584 or DIN 43710, customer-specific sensor characteristics can also be defined, through the input of value pairs (user-defined linearisation). Through the configuration of a sensor with redundancy (dual sensor), on a sensor failure it will automatically change over to the working sensor. Furthermore there is the possibility to activate Sensor Drift Detection. With this, an error signal occurs when the magnitude of the temperature difference between Sensor 1 and Sensor 2 exceeds a user-selectable value.

The field temperature transmitter also has additional sophisticated supervisory functionality such as monitoring of the sensor wire resistance and sensor-break detection in accordance with NAMUR NE89 as well as monitoring of the measuring range. Moreover, this transmitter has comprehensive cyclic self-monitoring functionality. Via the display it is possible to show range alarms as well as MIN and MAX values. The field temperature transmitter is available in various field-housing variants. Stainless steel and aluminium can be specified. It can be mounted directly on a wall. A pipe mounting kit is also available for fitting to pipes with a diameter of 1... 2". The field temperature transmitters are delivered with a basic configuration or configured according to customer specifications.

The model TF-LCD digital thermometer is used for industrial temperature measurement in the cooling and refrigeration industry as well as in heating technology. The easy-to-read LC display is powered by a built-in battery or an integrated solar cell.

A measuring line with a maximum length of 3 metres enables the display to be installed flexibly and independently of the measuring location.

The model DI25 digital indicator is a multi-function, competitively-priced instrument for a wide variety of measuring tasks.

The multi-function input has 18 different input configurations, which can be selected via the rear connections and also by selection of the appropriate input signal within the instrument configuration.
In this way it is possible to connect both transmitters with current or voltage signals and resistance thermometers or thermocouples to the same instrument.

The measured values can be retransmitted for further processing via an analogue output signal (4 ... 20 mA).

The basic version of the DI25 indicator features three alarm outputs. Instruments with the optional DC 24 V transmitter power supply have two alarm outputs available

With the high ingress protection of the front panel (IP 66), the DI25 digital indicator can also be used under extreme operating conditions.

All configuration and programming can be carried out through the front-panel keys.

The model DIH10, DIH10-Ex integrated digital display module (digital indicator) is a universal, configurable, current loop display for fitting to electrical thermometers.

The robust, compact display is only applicable where a standard signal of 4 ... 20 mA is already available. When used with the housing versions, it can be an on-site display for the entire industrial sector.

Combined with the ability to rotate the connection head and the large 4-digit, 7-segment LED display is easily readable from any direction.

In order to make the electrical connection, the current loop display is simple and easy to open. Buttons provide a user-friendly configuration of the display range.

To operate the connection head with a model DIH10, DIH10-Ex digital display module, a transmitter (4 ... 20 mA) for the measuring point is a precondition.

The DI30 digital indicator has been developed specifically for the display of measured values from electronic transmitters, such as pressure transmitters and temperature transmitters. It offers various input configurations for 0/4 ... 20 mA, DC 0 ... 5 V and DC 0 ... 10 V standard signals, which can be selected through the terminal configuration and input selection within the instrument configuration.

Thus, as an alternative, transmitters with current or voltage signals can be connected on the same instrument.
Using the transmitter power supply, current loop sensors (2-wire) as well as 3-wire and 4-wire sensors can be operated. The transmitter power supply is galvanically-isolated from the measuring input.
Two alarm outputs are available.

In addition, the indicator offers the possibility for sensor calibration and linearisation of up to 10 points. This makes further adaptation to different sensor signals and application requirements possible.

The standard features are completed with the adjustable sampling and display rates, and the input offset, for correcting zero offsets and sensor drift. Similarly, functions such as HOLD and TARE are included. Unauthorised alteration of the set instrument parameters can be prevented via different user levels, in conjunction with a freely-selectable access code.

All configuration and programming can be carried out through the front-panel keys.

The model DI35 digital indicator is a multi-function, and very accurate instrument for a wide variety of measuring tasks. It is available in two different versions:

• DI35-M
  The version has a multi-function input with 29 different calibrated input configurations that can be selected via terminal connections and the input signal in the instrument configuration. The display can permanently show the MIN or MAX value. Moreover, a totalizer function is integrated.
• DI35-D
  The version is equipped with two inputs for standard signals (0/4…20 mA and DC 0…10 V) that can be used in any combination. The display can show one of the two input signals or a calculated value. Calculations can be made by means of the four basic arithmetic operations (+ - * /) and an additional constant multiplier.

In addition, both versions offer the possibility to calibrate sensors and linearise using up to 30 points. This allows further adaptation of the displayed values to different sensor signals and application requirements.

The standard features are completed by a transmitter power supply, a HOLD function and a TARE function for the correction of offset shifts and sensor drifts. The sampling rate and display time can be configured and the display can be dimmed. Unauthorised alteration of the set instrument parameters can be prevented via different user levels, in conjunction with a freely selectable access code.

Optionally available are up to four freely programmable switch contacts, an analogue output signal and a serial interface.
