Smart Digital MODBUS pH & ORP Sensors and Touchscreen Controllers

immersiona.jpg (13140 bytes)
  • Smart digital MODBUS RTU pH & ORP sensors always send out temperature compensated and calibrated process values
  • Plug and play MODBUS RTU pH & ORP sensors can be hot-swapped in the field means no special training is required for operators to change out sensors
  • Process values, calibrations and analytic information available via MODBUS RTU (a.k.a. as MODBUS over RS-485) and MODBUS TCP (a.k.a. MODBUS over Ethernet) when paired with touchscreen controllers
  • Smart digital MODBUS RTU pH & ORP sensors can be connected to any PLC that can act as the MODBUS RTU master. No local transmitter is required if one is not desired (direct to PLC or SCADA) and/or if a local HMI is already present at the installation site.
  • Configurations are available which are suitable for use in hazardous Class I, Division II locations as well as Explosion-Proof EX areas with ATEX certifications.
  • Menu-driven color touchscreen controller allows for intuitive interface to sensors including support for all calibration functions as well as setup of analog outputs (4-20mA or 0-10VDC), programmable contact relays, datalogging as well as email notifications for trigger events to allow for proactive maintenance.
  • Full remote access capabilities to both the HMI for remote troubleshooting and monitoring as well as remote download of logged data mean significant savings for support and maintenance of commissioned sites
  • Multichannel turn-key ready pH & ORP measurement and control systems up to 6 channels in a single package allow for very cost effective per channel costs without compromising any of the advanced Industrial Internet of Things (IIoT) feature set.
  • Fast booting low power smart MODBUS RTU sensors are ideal fit for intermittent operation from remote wireless dataloggers running on batteries
  • Compact battery powered handheld communicator allows for use of Smart digital MODBUS RTU pH & ORP sensors anywhere in the field for spot measurements as well as calibration & setup at any location of your choosing. Calibrations need not be performed out in the field with the instrumentation but rather at any location that is most convenient for the facility and staff.
