Finding a long-term, stable supplier for sensors has been difficult – until now. Announcing Bourns® Precision Sensor (BPS) products. Trust Bourns for quality environmental sensors that offer proven reliability. HVAC, industrial, vehicle and low to medium risk medical device* designers can select from a full line of pressure and humidity sensors with strong dependability for a wide range of applications – for those with precision and ultra-low differential pressure monitoring needs to systems that operate in high temperature and harsh environments.

High sensitivity for ultra-low pressure ranges
Harsh air, liquid and gas media compatibility
Low TEB (Total Error Band) over the calibrated temperature range
Extremely stable performance over lifespan of product
Long-term drift—allows operation in conditions that typically cause most sensors to fail
Extended temperature range (-40 °C to +150 °C) model options
Custom port configuration and calibration available

Known for our superior customer service and knowledgeable technical support, we invite you to leverage Bourns’ extensive experience and long-term commitment to customers. Discover the difference working with Bourns can make in meeting your high sensitivity, long-term reliability and extended temperature capability feature requirements in your next design.
