CCP Standard Preamplifier with Microdot Connector GRAS 26CK 1/2”

Typical applications and use

• For use in confined spaces
• High-frequency measurements
• High-pressure measurements
• Sound intensity measurements
• Near-field measurements
• Anechoic boxes
• Hearing-aid measurements

Design

• The small, ceramic thick-film substrate in the 26CK has a very high input impedance and is shielded by a guard ring, which minimizes the influence of stray capacitance and microphonic interference.
• The 26CK is delivered with Generation II TEDS. The calibration data is programmed into the built-in TEDS according to IEEE 1451.4 using UDID I27-0-0-0U. If your measurement platform supports Transducer Electronic Data Sheets you will be able to read and write data like properties and calibration data.
• Generation II TEDS chip (DS2431) may require updated system software.

It can be used with the following GRAS prepolarized microphones:

• 40AE ½” Prepolarized Free-Field Microphone
• 40AD ½” Prepolarized Pressure Microphone
• 40AO ½” Prepolarized Pressure Microphone,High Frequency
• 40AQ ½” Prepolarized Random Incidence Microphone

The 26CK has an integrated Microdot output connector.

The casing is made of stainless steel for maximum strength and durability.

Calibration

• Before leaving the factory, GRAS products are tested and calibrated by GRAS, and an individual test certificate is included with the product.
