MPS-TEC

Product catalog summary

Overview: The document describes the MPS-TEC Multilevel-Conductivity-Chain, a robust and maintenance-free multiparameter probe designed for high-resolution monitoring of saltwater intrusion dynamics in groundwater. The device is constructed from 1.4539 stainless steel, ensuring resistance to saltwater, and is compatible with SEBA data loggers.

Specifications:

Design: Slim design with a diameter of 22 mm, suitable for observation wells down to 1" diameter.
Segments: Available with up to 7 MPS-TEC segments and customizable cable lengths.
Compatibility: Works with SEBA data loggers such as SlimlogCom and UnilogCom.
Upgrade Options: Can be upgraded with a pressure sensor for water level measurements.

Technical Data:

Temperature Measurement: Uses NTC 30 sensor with polynomial linearization, measuring range from -5 to +50 °C, accuracy of 0.1 °C.
Conductivity Measurement: Utilizes a 4-electrode measuring cell, with a range of 0-200 mS/cm and accuracy of ± 1 μS/cm at 0-200 μS/cm range.
Housing: Made from 1.4539 stainless steel, dimensions Ø 22 mm, length 320 mm, protection class IP 68.
Interface: RS 485 (SHWP) standard, with a power supply requirement of 4-15 VDC.
Operating Conditions: Suitable for temperatures from -5 °C to +50 °C, non-freezing, and mounting depths up to 1000 m.

Applications: The MPS-TEC is ideal for high-resolution spatiotemporal monitoring of saltwater intrusion dynamics in coastal groundwater environments.
