Omron Electronic Components Europe has added a new piezo-resistive gauge pressure sensor featuring an extended pressure range as well as low power consumption and small size.

The 2SMPP-03 MEMS based pressure sensor is seen as ideal for medical applications such as negative pressure wound therapy (NPWT) as well as leak detection, movement control, level indicators, home appliances and industrial control instruments. It offers precise measurement between -50kPa to +50kPa, complementing the 2SMPP-02 with a 0 to 37kPa range.

The devices share exceptionally compact external dimensions, of just 6.1mm x 4.7mm x 8.2mm. They offer a reduced offset voltage and span dispersions of ±4mV and 3.1mV, which makes trimming unnecessary. The low power consumption of 0.2mW associated with a drive current of just 100 micro-Amps provides significant energy savings. The specifications include a non-linearity of less than 0.8% of full-scale and a hysteresis of 0.5% of full-scale. Another outstanding feature is low temperature influence span of +/-1% and offset of +/-3% of full-scale, says the company.
