The Columbia Models SA-107WPBI and SA-107WPBIHP are waterproof versions of Columbia's popular Models SA-107BI and SA-107BIHP. These waterproof sensors are designed with an output circuit configuration made for use with 4-20 mA data transmission systems used extensively in industrial installations in order to transmit data over long distances in rough environments.

The Models SA-107WPBI and SA-107WPBIHP contain special desensitization circuitry to provide accurate static acceleration data while in substantial vibration environments. The incorporation of Columbia's patented HP suspension system into Model SA-107WPBIHP provides added accuracy and ruggedness. A single +15 volt supply powers both the sensor and 4-20 mA line driver. Consult the factory for customized versions of these sensors.
