COVID-19 operations: We are maintaining manufacturing capacity, prioritizing orders related to essential services and infrastructure -- NDT, oil, gas, aviation, aerospace, rail, utilities, defense, medical research, etc. Located just north of the labs in Livermore, California, we perform all assembly, testing, and shipping in-house. We began implementing decon, PPE, and distancing procedures in February 2020; our staff is working remote when possible, staggered shifts in separate areas when on site, and spraydown in between. Inventory levels for most parts and raw materials are normal, and we have at times been able to make PPE components for area clinics and first responders. Please feel free to contact us via e-mail or phone with any questions or special requirements. Take care of your family, self, and community; we will get through this together.

Protected Element Transducers

Protected Element Transducers are used for rough, irregular or hot surface.  There are three different types of protective faces.  Protected Membrane, Protected Wear Cap, and High Temperature Delay Line.  These transducers are available in both G series and S series with either straight or right angle BNC connectors.  Lemo connectors may also be available.

Protected Membrane(PM) is designed to improve coupling with the rough-surface test materials.

Protected Wear Cap(PW) prevents the transducers from being damaged by the rough-surface test materials.  The cap is replaceable.

High Temperature Delay Line(HDL) is used for hot surface testing.  The temperature can be allowed up to 900°F.
