GENERAL DESCRIPTION
The Pax Lite RTD Meter accepts standard RTD inputs and precisely linearizes
them into temperature readings. A full 4-digit display accommodates a wide
range of temperature inputs. State-of-the-art digital circuitry virtually eliminates
errors due to drift.
The meter features a readout choice of either Fahrenheit or Celsius with 0.1 or
1 degree resolution. English Style display prompts and front panel buttons aid the
operator through set-up and operation. Programmable digital filtering enhances
the stability of the reading. All set-up data is stored in EEPROM, which will hold
data for a minimum of 10 years without power.
The meter provides a Peak (HI) and Valley (LO) reading memory with
selectable capture delay time. The capture delay is used to prevent detection of
false Peak or Valley readings that may occur during start-up or unusual process
events. The Peak and Valley readings are stored at power-down to allow
monitoring the process limits over any length of time (shifts, days, etc.).
The meter has several built-in diagnostic functions to alert operators of any
malfunction. Extensive testing of noise interference mechanisms and full burn-in
makes the meter extremely reliable in industrial environments. The front bezel
meets NEMA 4X/IP65 requirements for wash down applications.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired. Do not use this unit to directly
command motors, valves, or other actuators not equipped with safeguards. To
do so, can be potentially harmful to persons or equipment in the event of a fault
to the unit.
