Introduction To The Icas And Icah Range Of In-Cell Amplifiers - Mantracourt ICAS Series User Manual

Introduction to the ICAS and ICAH Range of In-Cell Amplifiers

Two new families, the ICAS (industrial stability) and ICAH (high stability) have been introduced into the Mantracourt
range of In-Cell Amplifiers. They offer improved performance and easier installation over the original designs.
The following points detail the main changes:

The ICA1 and ICA2 output ranges have been changed to cover 0.1V to 10.1V and 0.1V to 5.1V respectively to
facilitate calibration and interpretation of the output level.
The linearity has been improved at the lower end of the scale (down to 70mV output).

Excitation is standardised at 5V DC on the ICA1,2,3,4 and 6.

The performance of the ICA family has been much improved over the operating temperature range by using
high performance, auto-zero amplifiers and low drift resistors.
The standard ('S') versions give a 200% improvement compared to the earlier versions.
The high performance ('H') versions are fitted with higher-specification resistors to offer a 400%
improvement over the earlier versions.

The user-selectable span resistor is mounted via two standard plated through holes in the printed circuit
board making it easier to change if required.
There is also provision for a second resistor (not normally fitted) to give an offset zero if required for
example, 5.1V ±5V for an ICA1.

All wire connections are via plated through holes instead of the single-sided pads used in the original design.
This allows all wires to enter from either side of the board resulting easier installation and improved joint
reliability.

Multi-layer printed circuit boards and additional filtering has been added to further improve the EMC
performance.

Faster and easier mounting/installation: The mounting hole size and position has been standardised on all
models and also provides the capacitive-coupling connection to the sensor body which further improves the
EMC performance.
The hole will accommodate a 2mm (#0-80) screw with adequate clearance for the head.
As this mounting method is compatible with our range of 'D-Cell' products, a single pocket design will
accept either digital or analogue conditioners.

An ATEX (Intrinsic Safety) certified version of the ICA5 has been introduced.

All variants are RoHS compliant.

All models have a reduced height of just 7.6mm. The diameter remains at 19.5mm.

A new model, the ICA6 has been introduced which will provide a ±10 Volt output from a uni-polar 15 to 28V
supply.

Non-interaction between the trimmers makes calibration easier and faster.
