Analytical Transmitter

M800 Multi-Parameter Analytical Transmitter

The Mettler-Toledo M800 transmitter series features premium Intelligent Sensor Management (ISM) technology measuring pH / ORP, optical DO, amperometric oxygen (DO as well as O2 gas), dissolved carbon dioxide, turbidity and conductivity. The analytical transmitter accepts any compatible combination of ISM sensors. Up to four channels of process measurement provides immediate Plug and Measure installation and operation, predictive sensor maintenance and dynamic lifetime status. The color touchscreen ensures intuitive operation, with user selectable control and alarm management.

M400 Transmitter G2 (ISM Transmitter)

The multi-parameter M400 transmitter series features Intelligent Sensor Management (ISM) technology and covers pH / ORP, oxygen (for measurement of dissolved oxygen or in gas), dissolved carbon dioxide, dissolved ozone, conductivity or GPro 500 TDL, depending on the type you choose.

The high-contrast black and white touchscreen together with four soft keys allows you to operate the Mettler-Toledo pH transmitter even in the harshest applications without compromising user ergonomics. The online diagnostic information with harmonized menu display lets you know when it is time to do maintenance or calibration of sensors equipped with ISM technology. The HART or FOUNDATION fieldbus communication protocol provides easy integration of sensor diagnostics into process control systems.

M100 Sensor Mount Transmitter: Digital Sensor Integration for Analog and Digital Biocontrollers

The M100 Sensor Mount (SM) is a single-channel, analytical transmitter. It allows the connection on biocontrollers of 1-wire ISM sensors for measuring pH, ampDO and CO2 or ISM RS 485 optical oxygen sensors. The M100 transmitter has a Bluetooth 4.0 interface which is compatible with the PC-based and mobile versions of iSense software. Two independent interfaces are implemented: two configurable 4/20 mA analog outputs and one digital MODBUS RTU. LEDs clearly indicate sensor status, alarms and warnings. ISM’s Plug and Measure feature minimizes the risk of installation trouble and simplifies sensor handling.

METTLER TOLEDO ISM

What exactly is ISM?

ISM®, a breakthrough technology from METTLER TOLEDO, allows users of process analytical equipment to benefit from accurate diagnostics that predict when sensor maintenance will be required, while also increasing production process safety.

It is a digital technology that incorporates intelligent algorithms into sensors and analyzers. The combination of on-board microprocessors and algorithms that actually learn from process conditions, simplifies sensor and analyzer handling and workflows. ISM delivers a level of performance that analog systems simply cannot provide, including:

  • Increased accuracy and measurement confidence
    With ISM the process parameter value is calculated directly in the sensor, resulting in higher accuracy than analog probes. Moreover, the digital signal is unaffected by plant conditions and is stable over long cable runs, providing you with greater assurance in your processes.
  • Online sensor diagnostics
    ISM sensors continuously check themselves for wear. Inside the probe sophisticated algorithms learn from process variables to calculate when sensor calibration or replacement will be due. The Adaptive Calibration Timer and Dynamic Lifetime Indicator allow you to use your resources more efficiently.
  • Easy, error-free operation
    ISM sensors store their own calibration data. They can be quickly and accurately calibrated away from the process in any suitable location. When they are connected to an ISM transmitter, this data is uploaded and the Mettler Toledo pH transmitter configures itself automatically.
