Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

Vaisala PDT101 differential pressure transmitter is designed especially for demanding life science and high technology cleanroom applications.The transmitter is ideal for incorporating into the Vaisala viewLinc Continuous Monitoring System to measure and monitor the critical environmental parameters as required in regulated environments. Zero and span adjustment screws are available on every PDT101 model. Both adjustments are accessible from the front of the unit.

Key Benefits

Easy to install

Easy mounting on a wall, DIN rail or panel. The transmitter’s has a compact design and is well suited for monitoring cleanrooms and adjacent corridors with LED indicator lights for quick and easy power status checks.

Simplified compliance
As part of the Vaisala viewLinc monitoring system, the PDT101 is ideal for regulated environments where continuous, documented and redundant data is a requirement.

Precision and flexibility
The sensor enables precise measurement and control in high performance cleanrooms. The PDT101 transmitter is available with voltage output (3-wire) or current output (2-wire).

Applications

PDT101 is ideal for for high performance cleanroom environments in the life science, semiconductor, and electronics industries. As part of the viewLinc system, it is highly suitable for regulated environments where continuous, documented, and redundant data is a requirement to meet FDA regulations. The compact design is well suited for mounting in a cleanroom or in the adjacent corridor with LED indicator lights for quick and easy power status spot check.
