Product catalog summary
Overview: The MST measuring set is designed for differential pressure measurement in gases and liquids, particularly in hot-water heating systems. It is suitable for both industrial applications and pressure distribution systems of air or other gases. The set is not intended for permanent connection to high-temperature media pressure circuits.
Specifications: The MST set includes a DMU-T gauge powered by a 9V battery, housed in an ABS plastic casing. It features a 3.5-figure LCD display with a differentiability of 0.1% from the nominal range. The set is available in three types: MST10, MST100, and MST1000, with nominal pressure ranges of 10 kPa, 100 kPa, and 1000 kPa, respectively. The maximum error is 1%, and the ambient temperature range is 0 to 85°C, transiently up to 100°C.
Operation: The device is operated via a folio keyboard with buttons for power, resetting, and time filtration. It includes a magnetic foil for mounting on ferromagnetic surfaces. The instrument can be equipped with an analogue output and is resistant to permanent short-circuit.
Instructions for Use: The device is activated by pressing the “ON-OFF” button. A “LO BAT” indicator signals low battery, necessitating replacement. Resetting is recommended after battery changes. The three-way valve must be handled carefully to avoid sensor damage.
Maintenance: Routine maintenance involves periodic battery checks and replacements. The device should be kept clean and protected from high temperatures, humidity, and mechanical damage.
Ordering Information: The set includes a DMU-T module, a 9V battery, quick-couples, hoses, and a plastic case. Options for analogue output and metrological verification are available. Orders must specify pressure range, unit, and analogue output settings.
Warnings: Minimize valve opening time to prevent overheating. Avoid freezing water in the system to prevent membrane damage. The device is for service measuring only and should not remain connected to a pressure circuit.

CRESSTO - MST series - datasheet - set for measuring differential pressure-1

set for measuring differential pressure The measuring set MST is intended especially for measuring pressure differences in hot-water heating systems. It enables direct measuring of pressure loss in whole objects or single branches and sections of hot water distribution systems. Obviously, it is possible to carry out similar measuring in systems with hot or cold water for industrial purposes or in pressure distribution systems of air or other gases. By means of this measuring set, it is also possible carry out checking measuring of pressure difference on plates for measuring flow. But it is not possible to carry out mathematical conversion of the measured values, eg. calculation of root, etc. Measuring is made by means of a special variation of the DMU-T gauge with additional three-way fittings. The instrument is intended especially for service measuring and is not recommended for permanent connection with pressure circuits, especially with high temperature media. The used materials enable measuring pressure in gases and liquids, which must be non-aggressive. The DMU-T gauge is fed from a lamellar battery 9V and is mounted into a plastic casing from ABS. Operation is realized by means of buttons on a folio keyboard, which are used for switching the instrument on/off, starting up possible resetting and switching on the time filter which enables reading the mean value at pulsing pressure on the input. The instrument is equipped with a magnetic foil on the back side for fixing on a flat surface from ferromagnetic material. As the additional fittings are relatively heavy and the connecting tubes are relatively tough, it is necessary to pay particular attention to its fixing. measuring of differential pressure in gases and liquids Digital data about the measured pressure are displayed on a 3.5-figure LCD display in units stated on the label of the instrument with differentiability 0.1% from the nominal range. Made-to-order instruments can be equipped with an analogue output with the nominal range 1V. Based on an agreement, the instrument can be supplied calibrated also to different pressure units. easy operation All parts of this set are well arranged in a practical box with plastic foam padding. battery power supply low consumption reasonable price

C € EMC - accords to CSN EN 61326-1 At the customer's wish it is possible to secure a metrological verification of the transmitters at an accredited Calibration Service Centre. ORDERING CODE INSTRUCTIONS FOR USE • The instrument is started up by a short pressing of the "ON-OFF" button. In case of insufficient voltage of the battery, the sign "LO BAT" will appear on the display. In such a situation the battery must be changed because it could cause distortion of the measured results. After the battery is changed, always switch on and off the instrument using the "ON-OFF" button. After a short...
