Reliable Conductivity Measurement in Process & Water
Conductivity transmitters are analytical transmitters designed for monitoring electrical conductivity levels within a given solution for industrial process, pharmaceutical production and water quality monitoring. Conversely, resistivity transmitters monitor how strongly a solution opposes the flow of electric current. Conductivity transmitters offer a reliable interface for process and water measurements including a user-friendly touchscreen interface for simplified operation.
Easy-to-Operate Touchscreen Display
Conductivity and resistivity transmitters are equipped with a user-friendly touchscreen disoplay and intuitive, menu driven navigation for simple operation in a wide range of environments.
Conductivity Transmitters for Harsh Environments
The robust design of select METTLER TOLEDO conductivity transmitters ensures solid operation through a touchscreen and durable soft key interface when gloves are required in harsh industrial settings.
Multi-Channel Conductivity Transmitters
When multiple measurements are required, multi-channel conductivity and resistivity transmitters allow the monitoring of multiple sensors with one conductivity transmitter for redundant measurement.
Plug and Measure Calibration Features
With iSense, pre-calibrate your sensors ahead of time to minimize installation risk. Once connected to a conductivity transmitter, your pre-calibrated sensor is ready to measure immediately.
Enhanced Process Reliability of Conductivity Transmitters
METTLER TOLEDO conductivity transmitters incorporate ISM technology to provide accurate, real-time status information and enhanced process reliability to reduce maintenance and simplify handling.
Transmitters That Offer More: Multi-Parameter Functionality
With multi-parameter functionality, METTLER TOLEDO conductivity transmitters offer lower cost per measurement point by monitoring multiple parameters using a single conductivity transmitter.
Conductivity transmitters play an important role in an analytical measurement loop by continuously monitoring and reporting conductivity measurements and sensor diagnostic data back to the user through a touchscreen interface. A conductivity transmitter acts as the user interface for an online conductivity or resistivity sensor, and all METTLER TOLEDO conductivity and resistivity transmitters allow you to integrate your conductivity measurements into your control systems using either an analog signal or industrial communication protocol.
There is a wide range of criteria that goes into selecting the appropriate conductivity or resistivity transmitter for your specific needs and functions. When considering your application, you should assess your environment, how many parameters are being measured, if there are single or multi-channel requirements, or if Intelligent Sensor Management (ISM) is necessary. METTLER TOLEDO recommends a discussion with a local sales representative to assess your needs and recommend the right conductivity/resistivity transmitter for your specific application.
Yes, conductivity and resistivity transmitters that measure multiple parameters at the same time are called multi-parameter transmitters. METTLER TOLEDO conductivity transmitters with multi-parameter capabilities help lower cost per measurement point while providing greater flexibility, less complexity, and less training and inventory.
Conductivity is measured in siemens per cm (S/cm). A conductivity of 1 S/cm is actually quite high, so most conductivity measurements involve solutions where conductivity is measured in mS/cm (thousandths of a S/cm) or in μS/cm (millionths of a S/cm). Resistivity, on the other hand, is the inverse of conductivity and is measured in ohm-meters. Resistivity readings are typically displayed in MΩ∙cm. A conductivity transmitter generally offers flexibility in how measurements are displayed.
There are three technology types of conductivity probe used for process or water conductivity measurement in a conductivity transmitter:
- 2-electrode conductivity sensor
- 4-electrode conductivity sensor
- Inductive conductivity sensor
Additionally, a multi-parameter conductivity transmitter will also accept sensors for other analytical parameters, reducing training efforts and transmitter inventory needs.
