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

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.
