385 Convectron® ATM Vacuum Pressure Transducers
Overview
The Convectron® ATM Transducer combines control electronics with a piezo-resistive diaphragm sensor and the proven Convectron sensor to provide a continuous measurement from low vacuum to atmosphere. The compact design is easy to install and operate and includes a set point relay activation at a defined differential pressure from atmosphere. The Convectron ATM Transducer eliminates the need for two sensors in those applications that require low pressure measurement and an accurate indication of differential pressure at atmosphere, such as vacuum system loadlocks.
- Wide range of pressure measurement from atmosphere to 10-4 Torr
- Accurate and repeatable differential pressure set point at atmosphere
- Compact, rugged, RF and noise-immune module
- DeviceNet version includes an optional local display

Features
The Series 385 Convectron Module contains a piezoresitive diaphragm gauge which has silicone and epoxy seals that can be susceptible to permeation by helium gas. If a helium leak detector is used, it will register helium due to the permeation of the gas through these seals. When the module is saturated with helium, this permeation can contribute to base pressure readings below 10-7 Torr. For other common gases, including air, the leak rate is not measureable on a common leak detector.
- Wide Measurement Range: Allows for monitoring of vacuum system performance continuously from atmosphere to 1x10-4 Torr.
- Differential Diaphragm Sensor Technology: Outputs an accurate and repeatable indication of differential pressure at atmosphere through a set point relay.
- All-Metal Packaging: Provides a high level of immunity to RF noise
- Process Set Point Relays: Relay contacts are provided to control other vacuum equipment and provide a relay output at the defined atmospheric differential pressure set points.
- DeviceNet Version: Provides high-speed access to pressure measurement and easy integration with other sensors and controls.
- Optional Local Display: The DeviceNet version provides an optional, 3-digit green LED display that can be programmed to display in Torr.
- Low Power Requirements: System integration is easy using standard low voltage DC power sources.
