The PPTE offers and explosion-proof pressure transducer where protection in hazardous locations is critical. It combines proven silicon sensor technology with microprocessor-based signal conditioning to provide an extremely smart pressure transducer.

Designed with a hermetically sealed, stainless steel construction, the PPTE operates in severe vibration, thermal and mechanical shock environments. The PPTE has many software features that support a wide range of applications.

Applications
Process Control - Chemical Refineries - Oil and Gas - Paper and Pulp

Class I, Div I, Groups B, C, D
Class II/III, Div I, Groups E, F, G
Temp. T6
Max Ambient = 70^oC
Type 4X

FEATURES and BENEFITS

High Accuracy: ±0.10% FS typical accuracy from -40 to 85^oC

Simplifies System Design: no additional signal compensation needed to gain the benefits of a very accurate sensor

Smart, Digital Sensing & Control

Efficient Data Acquisition: connect up to 89 units on a multidrop bus using built-in RS485 capability

Easily Interfaces: directly to a PC via communication ports

Closes the loop: smart PPT makes control decisions

Versatile and Configurable

Works with existing and new systems: all units have 0-5V analog and either RS 232 or RS 485 digital outputs

Isolation diaphragms handle most media: harsh gases or liquids

Operates in severe vibration, thermal and mechanical shock environments

Optimizes output: user-configurable pressure units, sampling, update rate

Flags problems: internal diagnostics set flags, provide alarms
