Greisinger GLMU 200 MP johtavuusmittamuunnin 2-napaisella elektrodilla 113970

The Greisinger GLMU 200 MP is a conductivity transmitter for industrial measurement of electrolytic conductivity. It converts the conductivity signal into a 4-20 mA current loop, enabling direct connection to PLCs, indicators, and control systems. The transmitter supports three selectable measuring ranges: 0.0-200.0 µS/cm, 0-2000 µS/cm, and 0-20.00 mS/cm, covering a wide spectrum of aqueous solutions. Automatic temperature compensation via an integrated Pt1000 sensor ensures accurate readings regardless of temperature fluctuations. The included 2-pole conductivity electrode with cell constant K=1.0 cm⁻¹ is suitable for a variety of applications. The device is housed in a robust ABS enclosure with IP65 protection, making it suitable for wall mounting in harsh environments.

Advantages

High accuracy of ±0.5 % FS ±1 digit (transmitter only), flexible range selection, and reliable 2-wire 4-20 mA output simplify integration. The automatic temperature compensation and adjustable reference temperature (25 °C) provide consistent measurements. The IP65-rated ABS housing ensures durability in industrial settings.
