AquaMetrix AM-ES-TX Wide Range Toroidal Sensor

AquaMetrix AM-ES-TX Wide Range Toroidal Sensor is used in processes where conventional contacting sensors may foul or corrode (the terms “electrodeless” and “toroidal” are used interchangeably for this type of conductivity sensor).

The AM-ES-TX consists of an ES1 sensor and an ES-BT. The ES-BT is the blind transmitter box potion of the ES-TX. The AM-ES-BT is the smart blind transmitter that provides accurate conductivity readings across the sensor’s wide range, 4-400,000 µS/cm! The AM-ES-BT outputs analog (4-20mA) in a customizable range or an optimized digital output.

The AM-ES1 uses a glass-filled polypropylene body engineered to expand and contract at roughly the same rate as the stainless steel insert, thus minimizing cracking from temperature swings that afflict more toroidal sensors. An embedded RTD temperature element enables automatic temperature compensation. The AquaMetrix AM-ES1 sensor can be mounted in a flow-through configuration or submersion mounted in a tank or open vessel. Toroidal conductivity sensors are constructed of two wire wound toroids encapsulated in a potting compound and encased in a plastic body. One toroid acts as a transmitter and the other as a receiver. An electric current is induced between the toroids through the process solution. This current is directly proportional to the conductivity of the process solution. The generously sized toroids give the probe an industry-leading cell constant of 1.6 for maximum
sensitivity.

Toroidal conductivity sensors typically measure conductivity values greater than 100 µS/cm. However, the AM-ES-TX can measure levels as low as 4 µS/cm.
