Flow Sensors

The SIF1010/1012 flow sensor from Servoflo Corp. (Lexington, MA) includes a MEMS thermal flow die that measures gas or liquid flow. The die has thermal isolation and a ceramic film coating to protect the component from abrasive wear. The SIF1010/1012, conditioned and stabilized so burn-in at the application end is not required, includes a medical-compatible, straight-through flow housing.

Accelerometers

Meggitt (Irvine, CA) has introduced the Endevco® 35B triaxial IEPE accelerometer. The adhesively-mounted 35B places three transducers (measuring acceleration in x, y, and z axes) and integrated electronics into a 0.235-inch, 0.55-gram cube. Sensitivities of 2.5 mV/g, 5 mV/g, or 10 mV/g are available.

Pressure Sensors

Measurement Specialties (Hampton, VA), now part of TE Connectivity, has released the MS5837-30BA, a low-power, compact, gel-filled pressure sensor with an I2C bus interface and high resolution of 2 mm. The device has a 3.3 × 3.3 × 2.5-mm ceramic- metal package. The pressure sensor features a delta sigma ADC that offers 24-bit pressure and temperature values, while using 0.6 μA. The sensor has a response time of 0.5 ms, as well as a pressure range of 0 bar to 30 bar in temperatures from -20°C to +85°C. The anti-magnetic, stainless-steel cap and silicone gel protect the internal electronics and provide water resistance. The I2C bus allows the sensor to interface with other microcontrollers.

Gas Sensors

ENMET (Ann Arbor, MI) has announced the GSM-60, a microprocessor-based gas monitor. The system incorporates an internal sample draw pump and gas sensors. The GSM-60 can be custom- configured, with both internal and external sensors for monitoring VOCs, dew point, oxygen, and CO, or a number of other target gases, including O3, HF, HCl, and Cl2. The monitor can also be connected to a range of remote 4-20 mA toxic or combustible gas sensor/transmitters.
