A20

The Additel A20 Series of Pressure Transmitters and Transducers are engineered for exceptional stability, accuracy, and reliability in harsh industrial environments. The high-performance, robust build of the A20 enables market-leading long-term stability backed by a 3-year guarantee. Its highly stable, glueless sensor module and hermetically sealed electronics also deliver exceptional reliability and stability in demanding applications. With high accuracy and extensive temperature compensation, the A20 provides outstanding performance across the full operating range.

The A20 is available in gauge, sealed gauge, and absolute configurations, with pressure ranges from -14.5 to 10,000PSI (-1 to 700 bar). To ensure easy integration, the A20 supports conventional analog output as well as RS485 Modbus-RTU for digital communication. Fast ASIC technology enables response times of <1 ms (1 kHz) and a switch-on time of <30 ms. Digital communication also allows for simple calibration through an app. Built for durability, the A20 features best-in-class construction designed to withstand high shock levels (1000 g half-sine for 1 ms per IEC 60068-2-27), vibration, and more than 10 million pressure cycles (0–100% FS at room temperature).

Additel is renowned for the long-term reliability of its calibration standards and portable calibrators, and the A20 family of pressure transmitters and transducers continues that legacy—delivering unmatched reliability, stability, and service.
