Safety Instructions 1.1. Use for Intended Purpose Only The PT-LE differential pressure transducer registers both differential pressure and positive/negative gauge pressure. The operational requirements on the rating plate and in the "Specifications" chapter - and the safe supply voltage in particular - must be kept to. -
Page 5: Symbols
Operating Instructions PT-LE 1.4. Symbols The symbols below in these operating instructions point to the risks, which could arise in handling the equipment: WARNING! It points to a hazard possibly extending from injures through to death should the instructions not be followed. -

3.1. Functional Description PT-LE pressure transducers are of the precision type and despite their sturdiness they should still be treated with care. Installation right next to heat and radiation sources e.g. radiators should be avoided as this may lead to measurement errors arising. -
Page 7: Connections For Two-Wire System
The 24V input makes it possible to activate a 3/2 directional control valve with the same signal, which switches the PT-LE's pressure inputs at zero pressure during the zero calibration process. In this case the zero point calibration signal must be applied until there is no doubt that the pressure has fallen to zero. -
Page 8: Configuring The Output Signal
Operating Instructions PT-LE Configuring the Output Signal The user can configure the PT-LE's output signal. This can be done in various ways Output SW Pos 3 SW Pos 4 Comments 0…10V Last 2…10V Last 0…20mA max. load 4…20mA max. load The two-wire model must be configured by the manufacturer. -
Page 9: Display (Option)
Operating Instructions PT-LE Display (Option) To show up the readings, the PT-LE can also be fitted out with a display. The readings will be shown in either Pa or kPa depending on the limiting value of the measuring range. The number of the measuring range selected is always shown on the bottom line of the display. -
