AquaMetrix ASTX Series Conductivity Sensor

The AquaMetrix ASTX Series Conductivity Sensor is a direct, 4-20 mA sensor that has a AM-2250TX transmitter enclosed into a 1 inch CPVC body. It has a programmable cell constant, temperature compensation, calibration and a 4-20mA output. Factory calibrated and three cell constants from 0.1 to 10 are available to cover large range of water sample. Integral automatic temperature compensation Pt1000Ω RTD is standard on all types and provides compensation to 25 °C. The temperature element is in close thermal contact with the liquid being measured to ensure fast response to changing temperature.

ow-through mounting incorporates a special compression fitting (AM-CFT-R5) which allows adjustable insertion length in 1.5-inch NPT fitting or in the side of a tank. This design avoids the nuisance of disconnecting the cell cable when installing or removing the cell for cleaning.

Submersion mounting is achieved via the AM-ARM-5 mounting hardware. Mounting hardware is available which includes a 4 foot length of CPVC pipe and a simple but versatile adjustable bracket for hanging on the rim of the tank.

A hot tap ball valve mounting assembly permits removal of the cell from process piping or from tanks without shutting down the system.

The AS-TX is just one of many TX series (4-20 mA output) sensors that work with the AM-2300 web-enabled controller or virtually any PLC.

The sensor is compatible with any off-the-shelf 1” NPT fittings and serves as a drop-in replacement in fittings designed for the previous iteration.
