JUMO MAERA S25 - Level Measuring Probe (401015)

Economical level measurement for up to 10m of water
Part Number: 401015
Call for pricing

The JUMO MAERA S25 level measuring probe can be used in tanks for hydrostatic filling level measurement for filling levels starting from 0 to 2.50 m up to 0 to 10 mWC (water column).
The ambient pressure is generally offset by a pressure compensation tube integrated into a cable. The level measuring probe features the cost-effective approach of encasing a standard cable in an application-specific protective tube. This allows the protective tube to be used for pressure compensation.

Further interesting information can be found in the "Liquid level measurement" brochure.

Features

  • Measuring ranges: 0 to 250 mbar, 0 to 400 mbar, 0 to 600 mbar, 0 to 1 bar relative
    (0 to 2.50 mWC (meters of water column), 0 to 4 mWC, 0 to 6 mWC, 0 to 10 mWC)
  • Piezoresistive silicon sensor
  • Temperature of medium: 0 to +50 °C
  • Sensor technology proven thousands of times over
  • 2-wire reverse polarity protection
  • Robust level measuring probe for internal installation

Customer benefits

  • Economical
    This device has been developed on the basis of sensor technology of the JUMO MIDAS pressure transmitter range, which has been proven thousands of times over. Digital compensation and calibration of the sensor module saves time and money. The small dimensions make optimum use of materials. A standard cable is encased in an application-specific protective tube. These features combine to offer outstanding value for the money.
     
  • Process reliability
    The full cycle in the fully automated measuring and calibration facility guarantees that each level measuring probe is of a high quality. The probe is based around a piezoresistive measuring cell, which is safe and reliable with a high overload resistance.
     
  • 2-wire reverse polarity protection
    Reverse polarity protection ensures maximum safety during startup in level measuring probes with a 2-wire output. This protects the measuring instrument from damage during startup.

Applications

Level and filling level measurement for

  • Rainwater cisterns
  • Gray water recycling
  • Heating oil and diesel oil tanks
  • Swimming pools (disinfectant: chlorine)
