In our last newsletter, we introduced the SM5XXX, SM6XXX and SM7xxx pressure sensors. Now we have 3 more new pressure sensors from SMI to share:
SM6250 is an ultra low analog pressure sensor for -50 to +50 mbar differential pressure with a 10x burst pressure. The sensor is shipped uncalibrated but has an internal ASIC for those who wish to calibrate the sensor. Accepting a 2.7 to 5.5V operation, the sensor measures pressure on the backside with protective gel on the topside to protect its electronic circuitry.
SM6844 is an absolute pressure sensor for 15 PSIA having an amplified analog output with a compensated temperature range of 0 to 85C. This eliminates the need for additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm.
SM1X21 is either a gauge, differential, or asymmetric pressure sensor with a 14-bit digital output (temperature output is included). I2C interface with a compensated temperature range of -20C to 85C. Dual ported vertical or horizontal ports.
Model 1221 is gauge, model 1321 is differential, and model 1421 is asymmetric.
FS4003/FS4008 Mass Flow Sensors
The
FS4003/FS4008 Mass Flow Sensors are manufactured using Siargo's proprietary MEMS flow sensor and packaging technology. The sensors are housed in 3 mm and 8 mm pipes with maximum flow rate of 5 SLPM and 50 SLPM. The enclosure is made of polycarbonate.
The maximum over pressure rating is up to 5 bar (73 psi) due to Siargo's unique MEMS sensor chip structure, special packaging technology and the rugged sensor housing.
The mechanical structure is designed for easy assembly as a manifold for process gas monitoring and control. The FS4003 is packaged in a flow channel diameter of 3 mm with a low pressure loss configuration and measure airflow up to 5 SLPM. Applications include leakage detection, particle counter and analytical instrumentation. FS4008 are packaged in a flow channel diameter of 8 mm and measure airflow up to 50 SLPM. It can be used in gas flow measurement and/or control equipment. Applications include electronic flow meter for anesthesia equipment, clean room gas flow monitoring, air samplers and gas analyzers.

The
ME780 family uses a hybrid technology and Metallux's chip-on-board expertise to have signal conditioning directly integrated on top of the sensor. Together with membrane media-compatibility, the sensors offer a compact solution and precise temperature compensation. The sensor is available in many pressure ranges between 0.5 to 600 bar, and delivers a ratiometric output of 0.5 to 4.5 VDC or digital I2C. Overvoltage, short circuit and ESD protection included.
ME790 and
MEP790 are monolithic piezoresistive ceramic pressure sensors. The Wheatstone bridge is screen printed directly on one side of the ceramic cell by means of thick film technology and signal conditioning electronics generate 0.5 - 4.5V ratiometric output. Pressure and temperature calibration are done electronically with the on-board ASIC and can be performed in bar (ME790) or in psi (MEP790). Various calibration ranges from 5 to 400 bar.
TheHYT271combines the advantages of a precise, capacitive humidity sensor with the high functionality of an ASIC.
Integrated signal processing provides relative humidity and temperature over the I
2C compatible interface as digital values. The module is factory calibrated and any further alignment by the user is not necessary. Both linearity and temperature drift are corrected by on chip calibration, providing excellent accuracy over a wide range of temperature and humidity.
HYT 271 has excellent chemical resistance and long term stability, even in areas of high humidity. The sensor is dew resistant. Plug-in type SIL connections with an SMD version available upon request. Evaluation kits are also available.
Measurement range of 0 to 100% rH, -40 to 125C
Accuracy ±1.8% rH and ±0.2C (HYT 271-H)
I2C interface - communicate with 126 sensors at one time
