The powerful and innovative transmitter with Profibus PA interface.

The pH 2100-PA is a transmitter with Profibus® PA interface and suitable for highly reliable and accurate pH and ORP measurements in many industrial applications. It is easy to operate and the large-size LC display provides a wide range of information. The measured value is shown in large characters and additional pictographs explain transmitter function and warn of any signal irregularities. The bus-powered transmitter is based on the FISCO model and can be installed in hazardous areas.

Description

The pH 2100-PA is equipped with a Profibus® PA interface allowing full two-way communication between transmitter and remote DCS. The instrument provides intelligence in the transmitter for advanced sensor capability. It is packed with a number of outstanding functions, such as continuous sensor and transmitter diagnostic, which guarantee reliable operation. Calibration can be carried out with Calimatic auto-buffer recognition or through manual buffer input. Entering pre-measured electrode data is also possible. The built-in sensor diagnostic continuously monitors the glass and reference electrode. Any failure is displayed by the "Sensoface". It can be wall-, panel- or pipe-mounted. The removable front door with the plug-in connection terminals allows easy access to the instrument for service or maintenance work.

Powerful communication in measurement technology.

The pH 2100-PA allows mapping of the individual function blocks according to the PNO profile for analytical devices, Version 3.0. The communication is according to protocol DP/V1. The instrument can be configured via the bus with the aid of a suitable engineering tool (e.g. Siemens PDM) or through the keypads on the instrument.

The pH 2100-PA offers:

cyclic and acyclic data transmission according to the protocol Profibus® PA DP/V1
interoperability of analytical devices
power supply according to FISCO (fieldbus intrinsically safe concept) for installations in hazardous areas
communication according to the profile for analytic devices V3.0

Features and Benefits

Operational safety and reliability

Continuous sensor and transmitter diagnostics and large LC display with pictographs provide maximum process safety.

Exact and reliable measurement

Continuous Sensocheck and Calimatic functions with automated buffer recognition result in highest measurement reliability.

Simple and cost efficient wiring and maintenace

The Profibus® transmitter is based on a two-wire concept with full bi-directional digital communication. Measuring values, status information and diagnostic functions can be monitored from a central control station.
