Model 1000 Terminal
Unit
The Model 1000 Terminal Unit is a solid state stand-alone device designed to
read the digital signal form the Model 1000 Digital Level Sensor and convert it
to an analog output. The intent is to enable the superior accuracy of the
Model 1000 DLS to be used in a system, which has only analog inputs available
for receiving tank level data. This unit can poll up to 16 Model 1000 DLS
and output to eight (8) analog signals based upon data received from the Model
1000 DSL. The analog outputs are user programmable for either level or
temperature from a particular sensor. |
DAC4 (4-Channel Output
Board)
The DAC4 is a solid state stand-alone device which polls the Model
1000 Digital level sensor and outputs a 4-20 mA analog signal for use by other
field data collection equipment. The intent is to enable the superior
accuracy of the Model 1000 level sensor to be used in a system which has only
analog inputs. The converter can poll up to four Model 1000 Digital Level
Sensors and output up to four analog signals based upon data received from the
sensors. |
Model 3005 Single
Channel Output Board
The Model 3005 Interface board is designed to provide a single analog output
from the Model 1000 Digital Level Sensor. It provides a 4-20 mA signal
output for the total fluid of the tank. This is an alternative to the
Model 1000 Terminal Unit. It is intended for locations requiring an
analog signal for the tank level where only one or two tanks are on location. |
