Transmitters MIDA-SG-12-05, MIDA-SG-12-06, MIDA-SG-12-072, MIDA-SG-12-081,
MIDA-SG-12-082 are of flash-mount type and ecologically safe.
In transmitters MIDA-SG-12 (with measured medium temperature range up to +300°C) the pressure transducer and the electronic unit are separated; they are electrically connected by cable of about 1 m long.
Transmitters MIDA-SG-12 and MIDA-13 are produced in ordinary and intrinsic safe (-Ex) modifications.
Transmitters MIDA-13-Fp are explosion-proof with flame-proof enclosure.
MIDA-SG/SA-13-C and MIDA-SG/SA-13-H series are high-precision industrial pressure
transmitters with microprocessor temperature compensation. The resultant overall accuracy in the overall working temperature range -40…+80°C is within 0.25 or 0.5 % FS.
High-temperature transmitters MIDA-SG-12-C, MIDA-SG-12-H are high-precision
transmitters with microprocessor temperature compensation. The resultant overall accuracy in the overall working temperature range is within 0.5 % FS. Accuracy of high-temperature transmitters is guarantied at the working temperature of measured medium.
Transmitters MIDA-SG/SA-13-Fp-Svp with 4-20 mA output have built-in surge voltage protector.
The pressure ports of transmitters can be made according to special orders of customer.
The electrical connections and pressure ports of transmitters may be made by terminal block with sealing gland straight (S) and angle (A) or by plug/socket (P).

Digital indicators MIDA-DI-202 digitally indicate the information about pressure, temperature or any other physical quantity, transmitted by two-wire 4-20 mA loop.
Indicators MIDA-DI-202 are produced both in ordinary and safe-intrinsic (MIDA-DI-202-Ex) versions.
Digital indicators do not need any additional power supply; they are connected in series with the transmitter and can be placed in any convenient position.
Multifunctional digital indicators have adjustable indication range and may be realigned to read from any sensor or an execution unit having 4-20mA output signal.
