Standard Preamplifier with SMB Connector GRAS 26CT 1/4”

Typical applications and use

• Confined spaces
• High-frequency measurements
• High-pressure measurements
• Sound intensity measurements
• Near-field measurements
• Anechoic boxes
• Hearing-aid measurements

Design

• Its small ceramic thick-film substrate has a very high input impedance, and is shielded by a guard ring to minimise the influence of stray capacitance and microphonic interference.
• The 26CT 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 GRAS 40BE and 40BD 1/4″ and 40AE, 40AD and 40AQ 1/2″ prepolarized microphones using the included GRAS GR0010 Adapter for 1/4″ preamplifier and 1/2″ microphone.
• The 26CT has an integrated SMB connector. SMB-to-BNC cables are available, also with angled SMB. The casing is made of stainless steel for maximum strength and durability.
