alpha-COND 500 משדר מוליכות דו-גידי דגם 24VDC ,4-20mA ,A-CON-500 alpha-COND 500
Product Features
 
v
New Design with Isolated Output - The alpha 500 series transmitter prevents output interference due to electrical noise or leakage from the input source. Cross talk between multiple transmitters in the same loop is also eliminated.
 
                          
v
Out-of-range Output Current Indicator - Monitor your process effectively using the optional out-of-range current indicator. When the monitored value exceeds the measurement
range, the alpha 500 Transmitter indicates an out-of-range measurement by emitting a 3.8
mA output current.
 
 
v
Hold Output Current Indicator - Use the optional HOLD output current indicator for your process control purposes. Configure the transmitter to emit the pre-set 22 mA output current to indicate ‘HOLD’ mode during calibration or set up mode.
 
 
v
Scalable 4/20 mA Current Output - Assign Conductivity values at 4 and
20 mA for better resolved output at chart recorder or other peripheral devices.
 
 
v
Custom Dual Display LCD - Primary and secondary display are available for simultaneous display of Conductivity and Temperature values. Allows instantaneous viewing of measured readings and transmitter set up configurations.
 
 
v
Easy Push Button Operation - Simply calibrate or adjust setup configuration with just a few touches of the buttons. The alpha CON 500 push-button offset adjustment makes calibration simple.
 
 
v
Temperature Compensation - Compensates variance in the measured readings due to temperature fluctuations, either Automatically (with Pt 100) or Manually (Process and Calibration temperatures can be set separately).
 
 
v
Panel or Wall Mount, IP65 Weatherproof Housing - The alpha 500 series transmitter has the
flexibility to be mounted on the wall or in a control panel. In addition, the IP65 rated housing
allows the transmitter to be installed outdoors or indoors. Mounting accessories are included
for both types of mounting.
 
 
v
DC Voltage - Transmitters operate on a 12 to 24V D.C. power supply and multiples can be installed in a serial loop. Operations are not disrupted even if one of the transmitters requires service.
