Load cell weight force measurement

• 0...14pH, -1000...+1000mV
• Output 4...20mA, 2-wire-technics
• 24VDC power supply, galvanically isolated

Technical description

The very small measuring amplifier for pH and Redox type M2920 converts the electrode signal directly to a 4...20mA 2-wire signal. The M2920 works with a resolution of 12 bit, is pre-calibrated and connected between the electrode and signal acquisition instrument (e.g. PLC). Programmable logic controllers (PLC) or other controllers can be connected directly.

The Input is galvanically isolated from the output and power supply. The robust housing confirms the protected class IP67 and allows application in rough environments.

Optionally a 3-wire temperature compensation up to 120°C is available. Electrodes with build-in temperature sensor can connected directly.
