MU Digital

Product catalog summary
Specifications:
The MU Digital differential pressure transmitter features a robust ring balance mechanism with dual ball bearings and factory-filled sealing fluid. It includes a 3 1/2 digit LCD display with a height of 12.5 mm and uses a Hall sensor for angle measurement. The measurement ranges from a minimum of 0...40 Pa (+/-20 Pa) to a maximum of 0...1.8 kPa, with various intermediate values available. The display units include Pa, kPa, daPa, mbar, mmWS, mmCE, and in.W.C. The operating temperature range is 0 to +50 °C, with a maximum accuracy error of +/-1.5% of the full scale or +/-1.5 Pa. The housing is designed for wall mounting with an IP42 rating, made of light grey polycarbonate with a black back panel. The device weighs approximately 2.8 kg.
Connections and Outputs:
Process connections are made via hose nozzles with an outer diameter of 8 mm. Electrical connections are through screw terminals in the connection box, with cable glands 2 x PG9/M16 with strain relief. Electrical outputs include 0-20 mA, 4-20 mA, and 0-10 V, with a load capacity of max. 680 Ohm (mA) or min. 2kOhm (V). Auxiliary power is 230 VAC, with options for 24/110/120/240/24 V AC~ at no extra cost, and 24 V DC- at an additional cost. The device complies with EMC limits according to EN50081-2 (emission) and EN50082-2 (immunity).
Ordering Information:
To order, specify the type (MU Digital), measurement range, and auxiliary power. Each unit is delivered with a calibration protocol.
Sealing Fluids and Overload Capacity:
The sealing fluid is factory-filled, with options including "Füllöl" (mineral oil, density 0.8 kg/l) for ranges up to +/-700 Pa, overloadable to +/-900 Pa, and "Galden" (synthetic oil, density 1.9 kg/l) for ranges over +/-700 Pa, overloadable to +/-2.1 kPa. Overload capacity depends solely on the sealing fluid used, not the measurement range. If overloads beyond +/-900 Pa (Füllöl) or +/-2.1 kPa (Galden) are expected, a bypass must be installed in the ring balance.
Measurement Ranges:
Custom measurement ranges are available at no extra cost, with a factory calibration protocol provided for each device. Examples include pressure, vacuum, and differential pressure ranges from 0 to 1,800 Pa and tension/pressure ranges from -500 to +500 Pa. Additional units such as mbar, mmWS, mmW.C., in.W.C., and mmCE are available without extra charge.
Housing and Installation:
The housing depth is 170 mm, with three lugs for bolt diameters up to 8 mm. Cable entries are two PG9 for cable outer diameters of 3.5 to 8.0 mm. Hose nozzles have an outer diameter of 8 mm, with recommended PVC clear hose dimensions of 7x1.5 mm or 7x2.0 mm.

Messbereiche, Sperrflüssigkeiten Überlastbarkeit (Dient nur als Info; die passende Sperrflüssigkeit wird werkseitig eingefüllt). Da jede Ringwaage individuell und auftragsbezogen kalibriert wird, sind beliebige weitere Zwischenmessbereiche ohne Mehrpreis lieferbar. "Füllöl" Mineralöl, Dichte 0,8 kg/l; für Messbereiche bis +/-700 Pa überlastbar bis +/-900 Pa Überlastbarkeit Die Überlastbarkeit ist nicht(!) vom Messbereich, sondern ausschließlich von der verwendeten Sperrflüssigkeit abhängig. Beispiel: Eine Ringwaage mit dem Messbereich +/-20 Pa (Sperrflüssigkeit: Füllöl) kann beliebig lange bis...
