Innovative Sensors

Kavlico has more than 50 years of experience in the design of innovative pressure, position, force and other specialty sensors and transducers for mission critical applications in harsh environments for Transportation, Building Equipment, Energy & Infrastructure, Food & Beverage, Medical as well as Aerospace & Defense markets.

Kavlico Pressure Sensors pioneered the electronic pressure sensor and transducer market. Focused on premium quality products, and adapting innovative pressure sensing technologies to meet customer needs, Kavlico Pressure continues to be a leader in creating pressure sensing solutions for a cleaner, safer, more comfortable world.

Our broad range of technologies, such as Thin Film, Ceramic Capacitive, Piezo-Resistive and Silicon Capacitive, allows Kavlico Pressure Sensors to provide cutting-edge measurement devices for a diverse number of applications within several market segments.

With more than 15 years of experience with Piezo-resistive Pressure Sensors Kavlico is one of the world's leading suppliers supplying millions of pressure sensors per year with this robust sensing technology used in many different safety and mission critical applications.

Kavlico's Piezoresistive (PRT) Pressure Sensors and Transducers use a backside PRT configuration that is compatible with most liquid and gaseous media. Due to it's small size and adaptability this sensing technology provides a cost effective and reliable solution for the most demanding applications. PRT pressure sensors are available as gage, absolute, sealed gage and differential pressure references mounted in either metal or plastic housings.

The P4050 (DPF) Pressure Sensor is used to optimize the reduction of particulate mater (PM) in diesel exhaust. For example, system back pressure is measured to determine when a diesel particulate trap or filter (DPT or DPF) becomes clogged. Back pressure rises as the amount of particulate matter increases. Recent regulations require exhaust gas monitoring and filtering in diesel engines to remove Particulate Matter (PM). Two common methods are Diesel Particulate Filter (DPF) monitoring and Selective Catalytic Reduction (SCR) systems. Kavlico has led the way in these areas and was the first to mass produce a differential pressure sensor for DPF that indicates to the system when it should regenerate or burnout toxic exhaust particulates.
