4 TO 20 mA 4 Wire
ANGLE MEASUREMENT SENSOR
PN 100094-01
The 4 to 20 mA sensor uses our standard ratiometric sensor, and adds a
conversion circuit board to give you the most accurate, lowest cost, and most versatile
four wire 4 to 20 mA sensor on the market today.
The load resistance between J3.4 and J3.3 should be between 100 and 500
ohms to ensure proper operation.
The voltage will swing from 2 to 10 volts at J3.3 as the output swings
from 4 to 20 mA. J3.3 and J3.4 must be allowed to float. A differential input
meter is recommended.
The red and green LED will switch at the 12 mA position within 0.3 mA.
This indicates that the sensor is level.
To select a range, other than the factory setting, remove the
jumper from J5, J6 or J7 and install a select resistor between J3.5 and J3.6 for various
output ranges, calculated as shown: R = (556K / desired range) -10K.
For Example:
If the desired range is +/-40 degrees, then the value would be
calculated as follows: R = (556K/40) - 10K=
3.9K
Note: Only one jumper of J5, J6, or J7
shall be applied at any one time.
The features of this unique sensor are LED alignment aid, onboard
selectable output ranges, infinite remote selectable output ranges and connection for
remote LCD readout.
