Page 7: Dimension & Installation
Dimension & Installation The ST-765SS-SO3 should be installed in the ST-007 stainless steel inline sensor tee assembly for optimum accuracy. Sulfite functions an oxygen and chlorine scavenger are highly susceptible to rapid degradation. Stainless steel is recommended to ensure minimal sulfite depletion between injection of treatment and the sensor. - Page 8 Pyxis inline sensors with fully integrated calibration, scaling and measurement protocol. When any Pyxis Lab sensor is connected to the UC-80 in RS-485 Modbus, the UC-80 automatically recognizes the sensor and configuration for immediate data display, data logging and communication.

Page 10: Quick 4-20Ma Start Up
Follow the wiring table below to connect the ST-765SS series sensor to a controller. *NOTE* The ST- 765SS-SO3 sensor comes preset at 0-5ppm range of measurement and output signal from the Pyxis factory. This may be altered to a maximum of 100ppm using the 4-20mA SPAN ADJUST feature with the uPyxis APP. -
Page 11: Calibration And Diagnosis
Calibration and Diagnosis by uPyxis Mobile App Connect and power the ST-765SS sensor using the MA-CR Pyxis Bluetooth adapter (P/N: MA-CR) as shown in the following connection diagram. The power should be sourced from a 24 VDC power terminal of a controller. - Page 12 Tap the discovered ST-765SS sensor to connect to the sensor. The uPyxis app can identify the sensor type if multiple Pyxis sensors are discovered in the scan. As shown in Figure 6, in the calibration page of uPyxis after connected to the sensor via the MA-CR Bluetooth adapter the current Sulfite, pH and temperature values will be displayed.

Page 13: Sulfite Calibration
ST-765SS-SO3 sensor, the user can perform a single-point according to the requirements of the application. Calibration of the ST-765SS-SO3 sensor for Sulfite should be done with the sensor inline exposed to active flowing sample water. Use titration method, colorimeter or fluorometer (i.e.. Pyxis SP-800 / SP-910 or Hach DR1300) to test the active (flowing) water sample in the flow tee assembly. -
Page 14: Ph Calibration
Measure for 1 minute and wait for the measurement result to stabilize before performing calibration, the high pH calibration standard value range acceptable for this step is 8.00-13.00 pH.

4.2.3 4-20mA Span The 4–20mA output of the ST-765SS-SO3 sensor is scaled as: • Sulfite: – 4 mA = 0 ppm – 20 mA =5 ppm Tap 4-20mA SPAN to change the Sulfite value corresponding to the 20mA output to a value below 100ppm as seen in Figure 21. -
Page 22: Calibration On The Controller
With the default sensor settings, the controller should be set to convert 4 mA to 0 ppm and 20 mA to 5.00 ppm for ST-765SS-SO3. Calibration of the ST-765SS-SO3 sensor for Sulfite should be done with the sensor inline exposed to active flowing sample water. Use titration method, colorimeter or fluorometer (i.e.. Pyxis SP-800 / SP-910 or Hach DR-1300) to test the active (flowing) water sample in the flow tee assembly of the IK-765SS-SO3 panel. -
