Honeywell's New Explosion-Proof Precision Pressure Transducer Convenient for RS232 and RS485 Digital Interfaces

MINNEAPOLIS, Minnesota, SEPTEMBER 15, 2000 - Honeywell today introduces the PPTE, which is an explosion-proofprecision pressure transducer convenient for RS232 and RS485 digital interfaces. The PPTE communicates through readily available terminal emulation software with user-configurable update rates and baud rates as fast as 120 updates/sec and 28.8k, respectively. The PPTE is approved for Factory Mutual (FM) and Canadian Standards Association (CSA) explosion-proofapplications that meet Class I, Groups B,C,D; Class II, Groups E,F,G; and Class III. Typical applications for the PPTE include process control; chemical refineries; oil andgas; and paper and pulp industries. The PPTE accuracy is ± 0.10% FS specified over the entire temperature range of -40 to 85°C (-40 to 185°F). The PPTE is available for gauge and absolute pressure measurements with full scale ranges from 10 to 3000 psi.

Designed with a hermetically sealed, stainless steel construction, the PPTE operates in severe vibration, thermal and mechanical shock environments. To handle harsh gases and liquids, the PPTE utilizes a stainless steel isolation diaphragm with an option of Hastelloy. The PPTE software has many user-selectable features such as baud rate/parity settings, continuous broadcast, ASCII or binary output, temperature output, deadband/sensitivity, update rates, pressure units, and many other features that support a wide range of applications. Every unit comes with 0-5V analog output for use in existing systems.

The PPTE product is based on proven silicon sensor technology combined with microprocessor-based signal conditioning to provide an extremely smart pressure transducer. The PPTE is manufactured at the Solid State Electronics Center located in Plymouth, Minnesota.

Honeywell Space Systems - with operations in Phoenix, Arizona; Clearwater, Florida; Houston, Texas, Minneapolis, Minnesota; and Toulouse, France -designs, develops, and produces data controls, momentum controls, mechanisms, isolation, electronics, guidance and navigation and control systems for manned and unmanned space applications.
