Description

LEX 1 – a precise and versatile digital manometer with the function of recording Minimum and Maximum values for calibration and testing. LEX 1 Ei is approved for use in hazardous areas. Data transmission from 128 devices can be carried out via the RS485 interface.

Pressure measurement and display on the screen are performed twice per second. The current pressure value is displayed at the top of the display, and the minimum or maximum value since the last reset is shown at the bottom.

LEX 1 is operated by two buttons. The left button allows you to turn on the device, select functions, and units of measurement. The right button can be used to confirm the selection of a function or unit of measurement, as well as to display the minimum and maximum values.

PR – is a relative pressure transmitter, zero reading at atmospheric pressure. It can be used to measure both gauge pressure and vacuum pressure.
PAA – is an absolute pressure transmitter.
PA – is a gauge pressure transmitter (zero at 1 bar abs.). It is suitable for use where atmospheric pressure changes can be neglected (for ranges above 10 bar) or where a hermetic sensor is required.
PD – is a differential pressure transmitter

Maximum tightening torque for connecting the pressure gauge to the process — 15 Nm
