The low-noise preamplifier for the acoustic emission (AE) sensors is an essential part of the larger installations, where there is a signal attenuation. The preamplifier gain is fixed to 20 dB. The power is supplied by a separated power jack 5.5 x 2.1 mm and is thus maximally prevent a distortion. The preamplifier BOTEG PREAMP20 is built into a compact aluminum boxe with BNC outputs type F.

The preamplifier BOTEG PREAMP20 is fully compatible with our ultrasonic sensors (see below for related products) and also with oscilloscopes TiePie Handyscope.

Our preamplifiers are customized - at the customer's request, we are able to adjust its mechanical property (a design, a box, the IP protection, the level of amplification, a by-pass amplifier, etc.) and its graphical property (a manufacturer's logo, color aluminum boxes, a filling, distribution connectors, etc.).
