Tunable Diode Laser
Tunable Diode Laser (TDL) measurement technology is recognized for speed and accuracy of measurement, and immunity to background gases. To this, METTLER TOLEDO has added the simplicity of use and low maintenance of in-line sensor design, plus advanced predictive diagnostics. The result is the GPro 500 series, a highly durable line of oxygen sensors for process and safety applications in chemical plant and petrochemical operations.
METTLER TOLEDO 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 transmitter configures itself automatically.
