The differential pressure transmitters of the 985M series are used for measuring differential pressure, positive pressure and vacuum.
They offer 2 pressure ranges which can alternatively be selected by a jumper. The IP65 body protects the pressure transducer even in difficult environments.
Monitoring gaseous, non-aggressive media. Possible areas of application are:
air-conditioning and clean rooms
building automation
environmental protection
fan and blower control
valve and flap control
filter and blower monitoring
fluid and level monitoring
control of air flows
For optimum adaptation to the pressure application, the
transmitter can be switched between two pressure ranges.
The factory setting is the sensitive range 1, which is selected
by fitting a jumper. Removing the jumper activates the
non-sensitive range 2.
The output signal of the 3-wire version is configurable. The
factory setting is for a 0 ...10 Volt output signal, but this can be
changed to 4 ... 20 mA by removing the jumper. The 2-wire
version is only available with a 4 ... 20 mA output signal.

The 984M differential pressure measuring transmitters cover a pressure range from 0...100 Pa to max. 0...250 kPa. To ensure optimum adjustment to the respective pressure-related application, the models are equipped with multiple jumpers.
A new feature is the selectable output signal of 0…10 Volt or 4…20mA, which the user himself can set by means of a jumper on site during the installation.
The new model can also be automatically zeroed quite easily by the user himself. This is done by simply disconnecting the measuring transmitter from the pressure and pressing a button.
The ability to select between two different pressure ranges is already known from the previous model. Version 984M.323104b, for example, allows the user to select between the pressure ranges 0...250 and 0...500 Pascal.
A key advantage offered by the 984M.3x3114b model is the option of equipping it with a 3.5-digit LED display, whose brightly illuminated red figures can also be easily read in difficult conditions.

PUC 24 Process monitoring device for clean rooms
Sensitive measurement technology
Demands for increased quality in nearly every area of industry have led to more and more processes being conducted under clean-room conditions. Ensuring these conditions means monitoring room pressure, temperature and humidity. The new PUC 24 process monitoring device from halstrup-walcher has been specially designed for just such applications.
In essence, the PUC 24 is a differential pressure transducer that utilizes an inductive measurement principle to provide very high resolution of 0.1 Pa at a retest precision of 0.1%. Cyclical self-calibration of the zero point ensures proper measurement stability. The measurement range of ±100 Pa is freely scalable. Also available are inputs for temperature and humidity sensors; these can be set from 0-10 V or from 0/4-20 mA. All measurement values can be clearly read on a graphic LCD. Additional contact outputs are available for separate alarm signals. The device communicates with the master control module via a Profibus. The housing designed for front-flush installation is particularly innovative. Function keys are integrated into a stainless-steel keypad that forms a single smooth surface along the front of the housing. A mounting frame put in place when setting up the clean room makes the PUC 24 easier to install – four screws are all you need. This solution is the product of practical experience and simplifies more than just installation: the simple mounting system makes it possible to remove units quickly and effortlessly for calibration purposes or when switching units to accommodate changes in the process.

PS 27
Basic sensor for simple applications - mounting on top-hat rails,
very little hysteresis, contact points, IP65 protection class.
The PS 27 differential pressure transducer is a basic sensor for simple applications with very little hysteresis, temperature dependence or zero-point drift.
In addition to differential pressure data, the PS 27 also records positive and negative overpressures, and is suitable for measuring air and all non-aggressive gases. Zero-point calibration can be performed via an external control signal. A jumper is available for selecting the output signal.
A built-in adapter for top-hat rails allows the PS 27 to be mounted on top-hat rails (e.g., in a control cabinet) with no additional accessories required. With the optional switching output, a visual or audible alarm can be triggered whenever values fall above or below a threshold parameter. The PS 27 is a simple, precise pressure transducer for applicati

MSI sensor interface IC
The MSI integrated interface IC is a multi-channel Sensor interface IC. It generates dynamically to a maximum of 3 Sensor signals by means of current- and voltage- controlled resistance bridges (among other things switch- selectable input sensitivity) and provides subse-quent evaluation systems with A/D- converted signals via digital interface.
Furthermore, the IC enables the equalization of temperature due to an on Chip integrated temperature measurement or loadable reference charts. As well it supplies connected Sensors also with power supply. The IC in particular distinguishes itself besides the on Chip integrated functionality by a high signal solution in the case of simultaneous stability as well as a low power consumption.
The IC is suitable for evaluation of differential Sensor signals, as those that are supplied by pressure Sensors, Hall Sensors and Sensors, that work according to the principle of a resistance bridge (e.g. extension bridges, Piezo or Magneto-resistive Sensors).
