Foreword

Thank you for choosing a Kistler quality product. Please read

these instructions carefully, so that you can take optimum

advantage of the versatile features of this product.

The information in this document is subject to change at any

time without prior notice. Kistler reserves the right to improve

and alter this product in the interests of technical advance-

ment without being under obligation to notify any individuals

or organizations of such modifications.

5. Voltage Supply and Signal Outputs

Voltage supply and analog signal outputs for pressure and

temperature are accomplished through the 8 pin socket with

M12x1 locking mechanism (A). The connection can be made

in various ways:

• Standard industrial cable (8 pin, M12x1)

 e.g. Kistler Type 4777A5 (5m)

• Connecting cable with BNC signal outputs for pressure

and temperature  Kistler Type 1200A179A3 (3m)

• Adapter cable for the connection to a Binder plug in the

case of previous utilization of an amplifier of Type 4618

 Kistler Type 4775A0,5 (0,5m)

In the event that a standard industrial cable is used, supply

and signal reception are to be executed in accordance with

the following pin assignment.

Note on voltage supply and GND wiring:

• Voltage supply must range between 10 ... 30 VDC.

Values above 30 VDC could damage the device.

Values below 10 VDC could lead to malfunctions.

• Supply GND (-) must not be connected with Signal

GND (-) of analog signal output.

6. Connecting Sensors

More recent sensor generations permit the direct connection

of the sensors (DS Types) to the amplifier. Older sensors can

be connected using a connecting cable ( Chap. 3).

When using Kistler sensors and adapter cables, the connector

configuration is standardized and need not be checked. The

following section can be skipped.

Connecting sensors from other manufacturers:

When using sensors from other manufacturers, the connec-

tion must be accomplished in accordance with the following

testing bridge definition:

Instructions when using sensors from other manu-

facturers:

• The sensor testing bridge is supplied by the amplifier

with 1 mA constant current. This requires recalcula-

tions of sensitivity and the sensor zero point (ZMO)

under certain circumstances

• In order to avoid temperature errors, the sensor

must be equipped with analog temperature com-

pensation

The Kistler Piezoresistive Amplifier Type 4624AK... is a versatile measuring amplifier designed for piezoresistive pressure sensors, offering universal application. Its primary function is to convert the output of piezoresistive pressure sensors into a usable analog signal (voltage or current) for further processing. A key feature is its automatic sensor identification capability, known as PiezoSmart®, which allows the amplifier to quickly adapt to a connected pressure sensor by reading its characteristic values from an integrated electronic data sheet (TEDS). This ensures high flexibility and process reliability in daily applications.

Function Description:

The amplifier processes signals from piezoresistive pressure sensors. It provides voltage supply to the sensor and outputs an analog signal representing pressure and, if applicable, temperature. The device supports various sensor types, including Kistler's own PiezoSmart® sensors (DS, S, V200S types) and sensors from other manufacturers. For PiezoSmart® sensors, the amplifier automatically configures itself based on the sensor's TEDS data. For older Kistler sensors or sensors without TEDS, manual parameterization via a web interface is required. The amplifier also includes features for zero-point adjustment, signal conditioning (e.g., low-pass filtering), and gain adjustment.

Important Technical Specifications:

Voltage Supply: 10 ... 30 VDC. Values outside this range can damage the device or lead to malfunctions.
Sensor Connection:
- 8-pin, M12x1 socket for voltage supply and signal outputs (Type 4777A5 cable).
- 5-pin Fischer socket (103 A054) for sensor connection (Type 4761B, 4763B cables).
Output Signals: Analog pressure output signal (voltage: 0-10 V or current: 4-20 mA) and temperature output signal.
Sensor Bridge Supply: 1 mA constant current for external sensors.
Ethernet Connection: RJ45 socket for amplifier parameterization via web interface.
Operating Temperature: Not explicitly stated, but implied to be suitable for industrial environments.
Dimensions: Approximately 108.6 mm (length) x 74 mm (width) x 34.6 mm (height), with an installation plate.

Usage Features:

PiezoSmart® Sensor Identification: Automatically reads sensor characteristics (TEDS) for quick setup with compatible Kistler sensors.
Manual Parameterization: For sensors without TEDS or older versions, parameters can be set via an intuitive web interface accessed through an Ethernet connection. This includes user-defined amplifier settings, conversion of signal outputs, digital display of pressure and temperature, simplified zero-point setting, digital low-pass filter, firmware update, gain adjustment, and locking the sensor to the amplifier.
Zero-Point Adjustment: Can be performed using pushbuttons on the front panel or via the web interface. This is crucial for accurate measurements and compensates for shifts caused by sensor installation (tightening torque), ambient temperature changes, or sensor aging. The adjustment process involves briefly pressing the "Offset Adjust" button, using arrow buttons to set the zero point, and confirming the setting. A reset function is also available to restore the zero point.
LED Indicators: Multiple LEDs on the front panel provide clear status feedback:
- Status LED: Indicates the overall operating status of the measuring chain (green for ready, orange for starting/no sensor, red for error).
- TEDS LED: Shows whether a PiezoSmart® sensor is connected and functional (blue for connected, flashing blue for lock mode/wrong sensor, off for no TEDS/defective sensor).
- Ethernet LED: Indicates network connection availability (illuminated orange) and data transmission (flashing orange).
- Power/Output LEDs: Indicate the type of analog pressure signal output (green for voltage output, green for current output) and if a zero balance is in progress (flashing green).
Pushbuttons: "up," "down," and "Offset Adjust" buttons on the front panel allow for zero-point adjustment and resetting of settings.
Installation: The amplifier can be securely mounted onto a fixed surface using the supplied installation plate.
Connectivity: Supports standard industrial M12x1 cables, BNC signal output cables, and adapter cables for compatibility with older amplifier types (e.g., Type 4618).
DHCP Mode: The amplifier can be switched to DHCP (Dynamic Host Configuration Protocol) mode for integration into a company's network, using a specific pushbutton sequence during power-up.

Maintenance Features:

Firmware Updates: Can be performed via the web interface, ensuring the amplifier remains up-to-date with the latest features and improvements.
Restoring Factory Settings: All user and network settings can be reset to their factory defaults using a specific pushbutton sequence during power-up. This is useful for troubleshooting or reconfiguring the device.
Repairs: Repairs are handled by Kistler's local sales companies, ensuring professional service and support.
Disposal Instructions: Electronic devices should not be disposed of with household waste. Kistler provides guidelines for returning disused devices to designated electronics disposal offices or contacting a Kistler Sales Representative for proper disposal.
