Sensors

 

ST-500

Series Inline Fluorometers

ST-700

Inline pH / ORP / Conductivity Sensor With Embedded Transducers

ST-730

Series Inline Turbiditmeters

  • Color and turbidity compensation for accurate readings, long-term stability, and less frequent calibration.

  • Typical maintenance cycle in months, not weeks or days.

  • Works with WiFi and Bluetooth adapters for one-press calibration with the SP-910, 700, and 400 tools, and for firmware upgrades via your smart phone.

  • Isolated 4-20mA output: no need for additional transmitter for easy connection with PLC and DCS.

  • Dual embedded transmitters in sensor housing: 4-20mA and RS-485 supporting MODBUS.

  • Large conjunction capacity (compared to replaceable electrode design) leading to longer service life.

  • Longer maintenance cycles with high contamination resistance. Eliminates the need of pre-amplifier and transfer signal directly in 4~20mA or digital protocol.

  • Enhanced robustness when controller is away from sample point.

  • Specially designed pH/ORP electrodes tolerant to short time frozen during shipment or storage.

  • Stainless steel solution grounding point on sensor to stay away from ground loop problems.

  • Dual-wavelength: white LED and IR LED 90° scattering to achieve more reliable and accurate reading in a complex flow system.

  • A small footprint compact design, similar to an industrial pH probe.

  • Isolated 4-20mA output. No need for additional transmitter for easy connection to PLC and DCS.

  • Isolated RS-485 output embedded for easy trouble shooting and calibration.

ST 730 Inline Turbidity Meter
  • Eliminates Color & Turbidity Interference!

  • ST500 = PTSA (0-300ppb)

  • ST500RO = PTSA for RO (0-40ppb)

  • ST525SS = Fluorescein for Boiler FW (0-60ppb)

  • 4-20mA & Modbus RS485 Connection

  • Wireless Calibration   Smart Phone or Pyxis SP Units

  • Probe fouling diagnostics through PC

CR-100/200 Corrosion Sensor
  • Digital  technology:  The  weak  LPR  signal  is

  • conditioned, amplified and digitized immedi­ately in the sensor, avoiding interference and attenuation caused by long-distance transmis­sion to the transmitter.

  • Anti-electromagnetic interference design.

  • Ruggedized design for harsh environments.

  • MODBUS  support  with  isolated  RS-485  com­munication. Easy connection to DCS.

WIFI Inline Bluetooth Adapter

Bluetooth

Wireless Ultrasonic Level Transmitter

The Pyxis LS-200 is a general purpose and innovative ultrasonic liquid level sensor that replaces float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling liquids in small, medium and large capacity tanks. These liquid level sensors can be used in either open or enclosed tanks. The sensor provides continuous level measurement up to 86 inches (2.2m) with a 4-20 mA signal output, RS485 and Bluetooth digital output, and can be configured via Pyxis free uPyxis® APP for both smartphone or desktop. The LS-200 sensor can be powered by a 24VDC external power source via the 10’ output and power supply waterproof cable provided. This noncontact liquid level sensor is well suited for corrosive liquids chemical or process tank
