Electromagnetic Concentration Transmitter MDM-137A

Simple-to-operate Two-wire-type Electromagnetic Concentration Analyzer/Transmitter for field installation, in a compact and rigid aluminum enclosure.

• Concentration measurement of highly corrosive solutions. Made for accurate measurements and a wide range of concentration (%) of strong acid/alkali solutions, such as HCl, H2SO4, and NaOH; the measurement range and temperature compensation range can be adjusted to meet the individual needs and specifications of our customers. The device provides a linear output of 4 to 20 mADC for concentration values.​​​​​​​

• All wetted parts of the detector, made of Teflon® PFA, are highly resistant to corrosion, heat, and pressure. Thus, the instrument is able to operate under extreme measurement conditions. All-purpose PVC detectors are also available.

• Less susceptible to deposits (contamination and bubbles). The detector, which has a toroidal shape, can prevent deposits and bubbles in solutions from forming on the surface, thus ensuring long-term and stable measurements.

• Output signals can be frozen during maintenance work. By switching to ST-BY (Stand By) mode, the output value is held at the value that was set before the mode was enabled, therefore preventing disruption to the control system.

• Measured value adjustment. The measured value can be shifted by a conductivity (concentration) value as demanded for the convenience of process operation. (Shift width: ±20% of the measured value).

• Self diagnostics. The instrument is equipped with a burn-out function. When the self-diagnostics function detects an error in the measurement system, such as the failure of the temperature compensation resistor or a computer error, the burn-out function provides notification of the problem by causing the transmission output to go offscale (upper or lower limit).\

• Automatically returns to measurement mode. If the unit remains in maintenance mode for 2 hours, it will be returned to measurement mode automatically.
