METTLER TOLEDO has announced the launch of digital sensors with ISM® (Intelligent Sensor Management) technology, which helps reduce installation, maintenance, and calibration efforts for the sensors to a minimum.
METTLER TOLEDO’s digital sensors with ISM® technology are equipped with an integrated chip in the sensor head that stores all relevant sensor parameters and algorithms for enhanced sensor diagnostics. The sensor stores all relevant data to enable fast start-up when connecting it to a transmitter. In fact, when a connection is made, the sensor is automatically detected and the system parameterizes itself.
The ISM® technology also allows for predictive maintenance. Its goal is to perform maintenance work only as often as necessary, i.e. to calibrate, service, and replace parts only when actually required. This necessitates a precise understanding of the behavior of sensors under a wide range of process conditions.
Calibration values and calibration history are stored in the integrated chip in the sensor head. This allows sensors to be pre-calibrated in the controlled environment of a maintenance shop or laboratory, and then stored ready for use.
METTLER TOLEDO’s digital sensors feature the K8S connector, which has IP68 degree of protection, making it ideal for harsh, humid environments. Also, the measuring instrument used with the sensor, the M700 transmitter, allows integration of up to three modules for pH/redox, oxygen, and conductivity.
The system is backward- and forward-compatible, meaning that transmitters with ISM functionality can also handle conventional analog sensors.
Additionally, data transfer between the sensor diagnostics and transmitter can take place over long distances via a coaxial cable, due to the low-impedance signal that is used.
