alpha-CON500
1/4-DIN 2-Wire Conductivity Transmitter with LCD
 This
isolated output 4-20mA industrial transmitter is a sturdy microprocessor-based
instrument that measures conductivity and temperature and transmits
its output via the 2-wire power supply loop. This transmitter has
many user-friendly features – all of which are completely accessible
through the water-resistant membrane keypad.
Ideal for connecting
to a PLC for advanced control systems it can also be connected to
a recorder for a low-cost documentation system. The instrument's housing
is designed with mounting holes for easy installation on plates, poles
or walls. Other features include:
-
User-Customization
through Setup Menu offers flexibility in matching the
transmitter‘s functions to
suit individual‘s specific requirements
-
One-Point
Online Calibration without shutting down the line
-
Output
Current Indicator for Out-of-Range and Hold Conditions
to avoid discrepancy in readings
-
Scaleable
4 to 20 mA Output for better output resolution for chart
recording and other peripheral devices
-
Nonvolatile Memory retains all stored parameters
and calibration data, even if power fails
-
Large
Dual Display shows conductivity and temperature simultaneously—features
clear multiple icons, set points, and status messages
-
Panel-
or Wall-Mount NEMA 4X Weatherproof Housing for outdoor
or indoor installation
-
DC
Power Operation ideal for use in power plants and commercial
sites; can be installed in serial loop.
