When combined with the TCSMA or TCSTX toroidal transmitters, Sensorex’s TCS3020 toroidal sensor offers a complete conductivity measurement system for cooling towers, seawater, and concentrated acids.

The TCS3020 toroidal inductive conductivity sensor is designed for optimal performance from 0-1,000mS.

It offers the dependability of toroidal technology, providing a non-contacting, inductive-type conductivity measurement.

As an inductive sensor, it is resistant to the corrosion, coating and fouling common to contacting conductivity sensors.

Sensorex said the sensor is designed for long-term deployment with no maintenance.

The rugged TCS3020 sensor is constructed from Noryl.

It has a wide solvent tolerance and temperature stability to 105C and operates up to 150psig.

It is either submersible through utilisation of the sensor’s 0.75in MNPT threads or can be installed in-line using custom flow cell model FC95C.

It includes a standard style ATC measuring element and a 20ft (6m) cable.

The TCS3020 sensor combines with the TCSMA or TCSTX toroidal transmitters to provide a complete conductivity measurement solution.

The reliable TCSMA transmitter is designed for online monitoring and is suitable for applications requiring a 4-20mA signal.

As a blind 4-20mA transmitter, it drives the inductive TCS3020 sensor and provides a two-wire 4-20mA output on the same current loop.

Featuring selectable measurement ranges, the TCSMA transmitter is suitable to use with the TCS3020 sensor.

Temperature compensation is adjustable from 0-4 per cent per degree Centigrade.

It features sensitivity to 0.1 per cent of span, repeatability to 0.2 per cent of span and non-linearity of one per cent of span for span greater than 3,000uS/cm and two per cent of span for span less than 3,000uS/cm.

Drift is less than one per cent of span per month, non-cumulative, and it is stable to 0.2 per cent of measurement range per 24 hours, non-cumulative.

The TCSMA offers temperature drift of 0.06 per cent of range per degree Centigrade, span or zero.

It is enclosed in a durable, weatherproof and corrosion-resistant NEMA 4X (IP66) enclosure.

It features a variety of mounting choices for wall, pipe or DIN rail installation.

The device is loop powered with 16-35VDC.

The TCSTX transmitter is a menu-driven, loop-powered (16-35VDC) toroidal conductivity transmitter with 4-20mA isolated output that is also suitable for use with the TCS3020 conductivity sensor.

The TCSTX can be used for on-line monitoring of water treatment applications and aggress process chemicals.

Featuring a user-selectable range, the TCSTX transmitter is configurable to multiple full-scale ranges: 0-2,000uS/2.000mS/20.00mS/200.0mS/2,000mS.

Sensitivity is 0.05 per cent of span or 0.1uS, whichever is greater.

Repeatability is 0.3 per cent of span, or 0.1uS, whichever is greater.

The TCSTX transmitter features a large dual-segmented, high-content display, which indicates conductivity and process temperature simultaneously.

Its four-key driven menu allows technicians to select ranges in the field.

The transmitter is housed in a NEMA 4X enclosure with multiple mounting configurations available.
