IPC707 244-707-000-012-A2-B1-C26.32-D1-E2-F20000-G1 signal conditioner

Description:

The IPC707 is a signal conditioner from Meggitt’s vibro-meter® product line. It is designed for operation with sensors containing a piezoelectric sensing element that provide a charge output and require an external signal conditioner (charge amplifier).

The IPC707 signal conditioner is a versatile and highly configurable device that converts and processes the charge- based signal from a piezoelectric-based sensor into a current output or a voltage output signal, suitable for transmission to a monitoring system via a standard current (2-wire) or voltage (3-wire) transmission cable.
The IPC707 is designed for operation with vibration measurement chains using CAxxx piezoelectric accelerometers and pressure measurement chains using CPxxx dynamic pressure sensors. It can also be used with other piezoelectric-based sensors and cabling assemblies that meet the required input characteristics.
Note: The installation of a CAxxx or CPxxx measurement chain using an IPC707 signal conditioner configured with a current output and a GSI127 galvanic separation unit, allows transmission over distances up to 1 km – longer than any other solution.
As shown in the Block diagram on page 3, the IPC707 signal conditioner includes RFI filters to protect the input and output against radio-frequency and other electromagnetic interference (EMI), optional hazardous area protection, a differential (symmetrical) charge amplifier, configurable high-pass (HP) and low-pass (LP) filters, an optional integrator to give a velocity output, a configurable amplifier and a configurable output stage to provide a current output or a voltage output, as required. Optionally, the IPC707 signal conditioner includes diagnostic circuitry (that is, built-in test equipment (BITE)) that is used to indicate problems with a measurement chain consisting of a sensor, cabling and the IPC707 signal conditioner.
The output signal from the IPC707 is an analogue signal consisting of a dynamic measurement component (AC) on a quasi-static diagnostic component (DC). When the optional diagnostics are used, the nominal value of the diagnostic component (DC) is one value to indicate normal operation, and other values to indicate problems with the sensor and/or cabling, or the signal conditioner itself. The machinery protection and/or condition monitoring system connected to the IPC707 can monitor the nominal value and provide an alarm to indicate a problem (non-normal operation).
An IPC707 signal conditioner with optional diagnostics continuously monitors the status of the measurement chain, which allows operators to always know the status of their machinery monitoring system – automatically and remotely. In this way, the diagnostics helps to ensure that machinery is operated safely and reliably, extending its life and reducing costs. Equally importantly, the diagnostics also make the IPC707 suitable for use in functional safety contexts, such as SIL 2 in accordance with IEC 61508 and PL c Cat 1 in accordance with ISO 13849.
The electronic circuitry of the IPC707 signal conditioner is incorporated in a moulded aluminium housing. The IPC707 can be installed using screws through the mounting holes in the body of the housing (same dimensions as an IPC704) or it can be mounted on a DIN rail using the optional DIN-rail mounting adaptor. The IPC707 housing also features removable screw-terminal connectors that can unplugged from the main body of the housing to simplify installation and mounting. For applications that require additional environmental protection against dust, oil and/or water, the IPC707 can also be installed in an ABA17x industrial housing.
The IPC707 signal conditioner is compatible with different piezoelectric materials and replaces the previous versions of the IPC704 signal conditioner (PNR 244-704-000-xxx).
