GENERAL DESCRIPTION
The features of the PAX Lite Series can be applied to measurement of
process variables. With its high sensitivity and programmability, the PAX
Lite Current Loop Meter can be set up for a wide variety of applications.
The PAXLCL can be used for most current loop meter needs for readout
of pressure, flow, temperature, level and other variables. The meter has
been specifically designed for harsh industrial environments. With NEMA
4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.
This allows the PAXLCL to be used in dirty, hostile environments and in
wash-down areas. The 3 1/2-digit bi-polar display (minus sign displayed
when current or voltage is negative) features 0.56" (14.2 mm) high, 7-
segment LEDs for easy reading.
