With its integrated transmitter and connection for diagnostic, the MAXIMAT is ideal to detect the liquid level and to give an alarm before the overfilling of a tank.Convenient to use with any electrically conductive, non-flammable, waterendangering liquids; even highly aggressive liquids. It is a perfect instrument to detect fluid in a double wall tank.

The transmitter MAXIMAT is designed to detect conductive liquids with aresistivity up to 5 kOhm/cm and a coupling capacitance towards ground ofmore than 50 pF. The liquids may not generate electrical insulating orconductive deposit. The MAXIMAT has 3 different outputs, factory built-in:

• Binary output to active optocoupler, numeric input
• Analog 0...20 mA output for any analog input of PLC

Main power supply: 15 ... 26 V DC; caution: DC current circuit should beprotected by a fuse of 250 mA. Power consumption: approx. 3 W
