Capacitec 4100-S Single Channel Capacitance Amplifier

## Capacitec 4100-S Single Channel Amplifier Card

The Capacitec 4100-S is a single-channel amplifier card designed for signal conditioning and amplification of capacitive displacement sensors. It is engineered for precision measurement applications requiring high resolution and low noise. The 4100-S is intended for integration into existing measurement systems or for the development of new sensor applications. This amplifier card is a foundational component within the Capacitec 4000 Series of modular instrumentation.

### Technical Specifications

* **Product Type:** Single Channel Amplifier Card
* **Series:** 4000 Series
* **Channels:** 1
* **Linearity:** ±2% of full scale (typical)
* Note: For enhanced linearity of ±0.2% of full scale, the 4100-SL model is available with an add-on linearization board.
* **Repeatability:** 0.01%
* **Signal Conditioning:** Provides signal conditioning for capacitive displacement sensors.
* **Gain and Offset Control:** Screwdriver-adjustable gain and offset controls are available.
* **Excitation Signal:** Features an amplitude drive adjustment pot for supplying a variable 15kHz excitation signal. An additional x1 to x6 screwdriver adjustable amplitude control is provided for a total of 3 x 6 = 18 V P-P drive amplitude capability.
* **Output:** Standard analog output is 0-10VDC. The 4100-SL model includes a “+ A / – A” sums amplifier.
* **Rack Mountability:** Designed for rack mounting with a 1.0-inch wide rack mountable front panel. Requires one slot within a 4000 Series rack.
* **Compatibility:** Compatible with all Capacitec sensors. The 4100-S is designed to operate with various probe diameter configurations and sensitivity ranges through simple recalibration.

### Electrical Characteristics

* **Power Requirements:** Operates with ±15VDC. Specific rack configurations may include integrated AC power supplies (-P100, -P115, -P220, -P240) or a ±15VDC/350mA power supply with optional 5VDC and -5VDC outputs.

### Interfaces

* **Data Acquisition and Computer Interface:** Designed for applications where computer interface and potential linearization are available. The 4000 Series racks offer three input/output terminals for computer or data acquisition interface on Centronics-style connectors or a 24-pin phone connector.
* **Analog Output:** 0-10VDC standard. The 4000 Series racks provide individual 0-10VDC analog outputs for each amplifier card.

### Physical Characteristics

* **Form Factor:** 2U high Euro-style board. Occupies a 1.0-inch wide slot in a 4000 Series rack.
* **Rack Slot Requirement:** 1 slot

### Compatibility

* **Sensor Compatibility:** Works with all Capacitec sensors.
* **System Integration:** Suitable for integration into existing measurement systems or for building new sensor assemblies.
* **Rack Systems:** Designed for use with Capacitec 4000 Series racks, such as the 4004 (4-channel) and 4016 (16-channel). A clock driver card (4100-C) is required to drive amplifier cards within these racks.

### Applications

* OEM and high-volume, multi-point applications.
* Precision measurement applications requiring high resolution and low noise.
* Systems requiring computer interface and post-measurement linearization.
