Pressure Sensors

Board Level
Board level, or PCB-mountable, pressure sensors use piezoresistive silicon die technology and are suitable for air or non-corrosive gases for pressure ranges from 1 to 500 PSI. Sensor packages include dual in-line, TO-8, TO-5, and disposable blood pressure sensors.

Transducers
Measurement Specialties produces a broad range of amplified output pressure transducers for everything from high volume OEM use to high accuracy applications. Measurement Specialties proprietary Microfused™ pressure transducers are designed for OEM applications that require high reliability in harsh conditions. Measurement Specialties' high performance line includes Ultrastable transducers for instrumentation, foil strain gage transducers for severe environments and miniature transducers used for automotive and aerospace testing.  

Low Cost Differential Pressure Guage

/ SERIES S2000

The Series S2000 is a low cost, diaphragm operated, differential pressure gauge.  The S2000 can be used in applications for measuring positive, negative, or differential pressure with an accuracy of 2%.  Standard applications include monitoring filter status, duct static pressure, room pressure, fan or blower pressure, paint booths, dust collectors, and cabinet purging along with many others.

Capacitive Humidity Sensor

/ MK 33

The MK 33 is a new developement which shows the creation of a technical product out of a vision with the special know-how in conjunction with advanced production technology.
 
Our Humidity Sensor which features a basic capacity of 300 pF provides a large Humidity-Temperature-Range and therefore it is suitable for many applications. The choice of the connectors between SIL-contacts and flexible wires opens the customer almost
unlimited possibilities in probe constructions.

Humidity / Temperature Measurement

HygroClip® is a high quality probe for the measurement of humidity and temperature. It is used in a wide range of applications including handheld instruments, dataloggers and transmitters. It provides digital and analogue output signals for both temperature and humidity. Humidity is measured in the range of 0…100 %rh, with an output signal of 0…1 V; the temperature is either -40…85 °C = -0.4…0.85 V (HygroClip S), or -40…60 °C = 0…1 V (HygroClip S3). The two versions are distinguishable by different probe colours. A digital one-wire data signal is also provided; this is ideally suited to OEM applications. The probes may be adjusted digitally by either software or handheld instruments. Calibration data is stored in an EE-Prom, therefore the probes can be used with any ROTRONIC display instrument or transmitter or even OEM instruments without the need for further adjustment.
HygroClip probes are available in many different versions.

HygroGen 1
Handheld instrument with integrated probe
0...100 %rh / -10...60 °C

HygroGen 2
Handheld instrument for interchangeable probes with 1 probe input,
0...100 %rh / -50...200 °C

Air Velocity Transmitter for HVAC Applications

EE65 air velocity transmitters are ideal for accurate ventilation control applications. They are operating on an innovative hot film anemometer principle. The E+E thin film sensor guarantees very good accuracy at low air velocity, which is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors.
EE65 series are available with current or voltage output, the measuring range and the response time can be selected with jumpers by the user.
Low angular dependence enables easy, cost- effective installation 

Air Velocity Switch

The Series 300 Airflow Switch is a line of solid-state highly reliable electronic switches, designed to monitor airflow in critical environments such as cleanrooms, semiconductor fabrication facilities, and operating rooms as well as in traditional electronic enclosures to warn of cooling degradation. These compact, easy-to-install units detect loss of airflow below a pre-programmed setpoint, and provide a fast and distinct warning of airflow deterioration. 

Designed to replace traditional "sail" or "vane" switches, the Series 300 offers unparalleled resistance to shock and vibration. The Series 300 may be either uni-directional or bi-directional. The uni-directional model discriminates between forward and reversed airflow, indicating a fault if the airflow direction reverses. The bi-directional model accepts airflows from either of two opposing directions.

The FlexiForce single element force sensor acts as a force sensing resistor in an electrical circuit. When the force sensor is unloaded, its resistance is very high. When a force is applied to the sensor, this resistance decreases. The resistance can be read by connecting a multimeter to the outer two pins, then applying a force to the sensing area. In the image below, the plot shows both the Force vs. resistance and Force vs. conductance (1/R).
Note that the conductance curve is linear, and therefore useful in calibration.

E+E Transmitter Series EE36 are specially designed for the measurement of water content in oil. EE36 is ideal for online monitoring of moisture in lubrication or insulation oil, which is very important for the long-term performance and adaptive maintenance of plant and machinery.
For instance, moisture affects dramatically the insulation characteristics of electrical transformer oil and therefore continuous monitoring is extremely important.

Humidity measurement in oil
Similar to the humidity in the air, the water content in an oil can be described by the absolute value in ppm or by the relative value aw: - ppm (mass of water / mass of oil) - aw (actual water content as fraction of the water content in the saturated oil) aw = 0 corresponds to water-free oil, while aw = 1 describes fully saturated oil. aw measurement with EE36 transmitter series is based on the outstanding long term stability and resistance to pollution of the E+E capacitive sensor elements series HC.
