The IST AG LV5 sensor is a flow-through biosensor and offers the possibility for multi-parametric measurements, since up to 4 analytes can be measured simultaneously (glucose, lactate, glutamine, glutamate). The sensor features a very small flow cell (1 µL) and therefore requires minimal sample volumes when used as an analyzer. Further advantages of the LV5 biosensor include: — Excellent long-term stability over a month in continuous measurement mode (lifetime varies depending on various factors, including the analyte concentration and buffer system (medium) amongst others) — Long shelf life (under appropriate environmental conditions) — Gamma and beta sterilization compatible — Suitable for continuous and analyzer measurement modes — Fast response time (depends on the buffer system (medium)) — Reference, counter and blank electrodes on-chip — Integrated flow cell (various volumes) Suitable for sampling systems in laboratories or food and pharmaceutical industries.

The SFS01 is particularly suitable for low flow velocities up to 3.5 m/s (in gases). It shows very fast measurement results of the flow rate as well as the flow direction. The Silicon Flow Sensor SFS01 offers three main characteristics: — Very fast response time <5 ms — Very low energy consumption — Easy system integration including temperature compensation Well-adapted channel geometries allow the performance of the sensor to be optimally aligned to the desired application. The SFS01 flow sensor is ideally suited for space-limited applications, but can also be easily upgraded to complete ready-to-use systems. Suitable application areas for the SFS01 flow sensor are flow measurements in battery-operated / portable devices, air conditioning technology (HVAC), automation technology as well as process and control engineering.

The 22DT series has been specially developed for use in bivalent vehicles (volume flow measurement when running on natural gas) and is homologated for the automotive industry. However, it also has other industrial applications. The NTC or PT temperature sensor located directly beneath the steel diaphragm reacts more quickly to temperature changes thanks to its special design. The pressure transmitters are protected against electromagnetic fields up to 200 V/m and output the measured values as a ratiometric 0,5...4,5V analog signal. The connections of the temperature sensor are fed out directly.

These miniature pressure probes are designed for measuring the flow and dynamic pressure of liquids and gases in pipelines. With diameters between 1,32 mm and 2,64 mm and a flexible yet robust cable, these probes can also be used in narrow ducts at depths of several metres.

The ASCO CO2 Flowmeter has been developed to accurately measure CO2 gas flow in closed pipes. The power unit, which supplies 230 V, operates a microprocessor controlled flow computer and one sensor. The ASCO CO2 Flowmeter is a complete system which is supplied fully calibrated and wired and therefore very easy to install.
