Heilind Electronics Expands Sensor Portfolio with P51 Series from SSI Technologies

Heilind Electronics, a premier distributor of electronic components worldwide, has added SSI Technologies’ MediaSensor P51 Series pressure sensors to its portfolio. Made in the USA, this family of sensors includes bulk micro-machined, absolute, sealed and gauge pressure sensors.

MediaSensor P51 pressure sensors are an excellent choice for both harsh and benign media, both due to their stainless steel construction and laser-welded design. Offering superior accuracy over an operating temperature of -40 to 105 degrees Celsius, these compact, robust sensors measure pressures from 3 to 75,000 psi. In addition, the sensors have strong immunity to EMI and other sources of noise that can affect electronic devices. In comparison, standard P51 pressure sensors were designed for 100 volts per meter EMI protection.

P51 pressure sensors are available in three electrical output options: The first two, featuring either a 4 20 mA or 1-5 V output, each operate with an input voltage range of 8-30 V. The third option, featuring a 0.5-4.5 V output (with or without overvoltage protection) operates with a regulated 5 V input supply. The current output (4-20 mA) is often chosen for industrial applications where the signal must travel long distances. This option presents higher immunity to electromagnetic interference, whereas the voltage outputs are chosen for shorter distances.

The MediaSensor P51 is especially useful in cases where the unit must be subjected to moisture or high humidity. This pressure sensor employs a cable overmold, which molds the cable jacket to the top of the sensor to prevent moisture from entering the transducer where the cable exits the unit.

SSI’s P51 Series is well-suited for a variety of automotive, industrial and commercial applications where cost, size and performance are critical. Ideal markets for these pressure sensors include material handling, HVAC and industrial, automotive and agriculture.
