STs020D4_20S Dissolved Oxygen & Temperature Transmitter

The STs Series of Submersible Water Quality Transmitters have an integrated preamplifier and a 4-20 mA "true 2-wire" transmitter.

Two independent channels simultaneously transmit a signal of dissolved oxygen (DO) and temperature - two cables for DO and two cables for temperature.

The compact design of the patented pHiConn (TM) keyless connection system - and the 316SS (optional titanium) and the Delrin construction - make the robust sensor / transmitter ideal for applications such as process control, data acquisition, data processing wastewater and groundwater monitoring.

Units can be submerged at 200 feet (approximately 100 psi).

Individual units can be combined to make redundant or multiparameter modules using the pHiKLIP (TM) system, patented by pHionics. The pHiKLIP (TM) system also allows units to be used in online applications (insertion) without fear of explosion.

As with all pHionics designs, the sensors / transmitters are designed with "ease of service" as the main objective.
