IST's New Micro Flow Sensor for Ultra Low Gas-Flow Applications
Flow Sens - MFS02
Innovative Sensor Technology has developed a new MFS02 micro flow sensor that utilizes thin film technology to layer platinum micro heaters and temperature sensors on an ultra sensitive polymer membrane. The MFS02 is capable of measuring the thermal mass flow of gases in a range from 0.001 to 2m/s (up to 50m/s), and has a chip temperature range of -40 to +150°C.
Polymer Membrane Construction
Using the same thin-film construction philosophy as IST's FS series flow sensors, the MFS02 employs a special glass substrate with an ultra thin polymer membrane to achieve extreme sensitivity. A high performance material, the polymer is characterized by outstanding thermal, mechanical and chemical behaviors. Reduced thermal conductivity of the polymer membrane leads to better thermal contrast and thus better sensitivity. Additionally, the sensor's glass substrate allows for a much higher operating temperature, making the measurement of larger flow rates possible.
Custom Sensor Applications
IST's development of the micro flow sensor allows customers to specify dimensions and resistor layouts to fit their own applications. The MFS02 features a rugged design that is well-suited for soldering, conductive gluing, or wire bonding. The sensor element can be mounted as an assembly on an electronic PCB or other carrier, and is ideal for mounting in a bypass flow assembly for differential pressure applications. An EVA Kit is available through IST for performance evaluation of the MFS02 micro flow sensor.
New Conductivity Sensor from IST
IST has developed a thin film conductivity sensor with the purpose of measuring the concentration of ions in an electrolyte. The conductivity of a substance can be measured by the voltage drop between two current electrodes, and thereby determined. The operating temperature range of the sensor is 0°C to +90°C and the measurement range is ~5μS/cm to ~20mS/cm. Furthermore, the IST conductivity sensor is offered with customer specific requirement for specific application needs.
Conductivity of an electrolyte depends heavily on the temperature of the medium, and therefore it is important to have an accurate temperature sensor for compensation. The thin film conductivity sensor, developed by IST, consists of two current electrodes, two measuring electrodes and a thinfilm platinum temperature sensor for temperature compensation. The temperature sensor, used for compensation, is an integrated PT100 or PT1000 with class A and B accuracy. The platinum RTD is applied on the conductivity sensor, directly at the point of measurement, for assured accuracy.
Applications in Water Quality
Conductivity sensors play an important role in determining water quality, and are able to measure the conductivity of most electrolyte solutions. The IST conductivity sensor is an ideal choice for water quality and waste water treatment applications, as well as many other applications.
