275 Mini-Convectron® Vacuum Pressure Transducers
Overview
275 Mini-Convectron® modular vacuum transducers features a compact design and dramatically reduced installation costs. These Granville-Phillips® vacuum gauges are ideal for applications where controller size and local control are critically important. The 275 series combines the industry-standard Convectron® gauge with electronics in a compact, modular design. They are capable of measuring from atmosphere to 1x10-4 Torr and are available with analog output, RS485 interface, and DeviceNet interface.
- Absolute pressure measurement from atmosphere to 10-4 Torr
- Compact and rugged all-metal package is virtually immune to RF interference
- All functions programmable through RS485 or DeviceNet interfaces
- Easy-to-read three-digit displays allow pressure readings at point-of-use
- Basic models come with one or two setpoint relays for use as a pressure switch

Features
Mini-Convectron® Sensor Technology
Mini-Convectron® sensors are a unique variation of thermal conductivity gauges where pressure measurement is based on the rate of heat loss from a sensor wire. Unlike traditional thermocouple and Pirani gauges that use only conductive heat loss, Convectron gauges take advantage of heat loss due to convection at higher pressures. This extends the range of accurate, repeatable measurement to atmosphere.
Digital Display Version
Display Side (Analog shown)
The digital display option provides an easy-to-read, 3-digit green LED display that automatically adjusts between two ranges (Torr and mTorr or kPa and Pa).
Digital Interface Version
Parameter Adjustment Side (DeviceNet shown)
Versions with digital communications provides RS485 or DeviceNet interface for easy compatibility with computer controlled processes.
Analog Output
The provided analog output is non-linear 0.375 to 5.659 VDC for 0 to 1000 Torr of N2. 11.5 to 26.5 VDC, 1.6 W max is required to power the 275 Mini-Convectron® vacuum pressure transducer.
