PL series liquid level pressure probes

PLH21 and PLH 27 liquid level probes are used for level measurement in piezometric pipes of subcutaneous waters, in bore-holes, wells and basins. PLH 48 liquid level probes are used mainly for measurement of polluted liquids such as sewage plants, ducts, water ways, etc. They operate with separate amplifiers with standard output signals.

Range 0 ... 100m (H²0)

Input 0,5 ... 4mA DC

Output signal 80 ... 1000mV DC

Non-linearity  ±0,25% or  ±0,5%

PLX21, PLX27 and PLX48 probes.

The gauge head of each of these level measurement probes contains a built-in amplifier with the following standard measuring signals.

Range 0 ... 100m (H²0)

Input 15 ... 36V DC

Output signal 4 ... 20mA DC, 0 ... 20rnA   DC, 0 ... 10V DC

Non-linearity  ±0,25% or ±0,5%

PLD type transducers are flange type and designed for liquid level measurement of polluted and cristallizable liquids in open tanks, or with application of pressure transducer in closed tanks. They require amplifiers with the following measuring signals:

Range 0...100m (H²0)

Input 0,5 ... 4mA DC

Output signal 80 ... 1000mV DC

Non-linearity ±0,25% or  ±0,5%
