Signet 8850-3 Conductivity/Resistivity Transmitter
*3-8850.090-3*
3-8850.090-3
Rev. K 11/12
CAUTION!
Remove power to unit before wiring
input and output connections.
Follow instructions carefully to avoid
personal injury.
1. Installation
ProcessPro transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.
Field mounting requires a separate mounting kit. The 3-8050 Universal kit enables the transmitter to be installed virtually
anywhere. Detailed instructions for fi eld installation options are included with the 3-8050 Universal kit.
1.1 Panel Installation
1.
The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel cutout, an adhesive
template is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch.
2.
Place gasket on instrument, and install in panel.
3.
Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.
4.
To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE.
Press quick-clips outward and remove.

  • Page 8: Calibration Procedure

    Calibration Procedure This instrument has been electronically calibrated at the factory. • Procedure A verifi es the accuracy and linearity of the instrument by simulating temperature and conductivity values with precision (±0.1%) fi xed resistors. • Procedure B is a wet calibration. This procedure uses the sensor input and NIST traceable test solutions. When done correctly, this procedure offers the most accurate system calibration.
  • Page 9 Temperature Coeffi cient Conductivity measurement is highly dependent on temperature. Temperature dependence is expressed as the relative change per °C, commonly known as percent/°C change from 25 °C, or slope of the solution. Slopes can vary signifi cantly depending on process solution type. The factory default temperature compensation factor is 2.00%/°C. Process solutions may require adjustment for maximum accuracy.
