Non-Contact Proximity Probes

Machine Saver probes are at the forefront of eddy current proximity probe design, are well acknowledged in the industry, and are compatible with all significant transducer producers. The American Petroleum Institute Standard 670 is completely complied with by the MS-Series probes (API-670). We guarantee the viability and durability of these proximity probes and associated systems for up to ten years, with a default warranty of three years that is extendable to five years at the customer's request. We are the only known American manufacturer of mass-produced vibration probes. In order to support a preventative maintenance program and machinery diagnostics, today's high-performance eddy current proximity sensors provide continuous condition monitoring information and trip monitored machines when necessary. Our leading proximity solutions provide full interoperability and exceptional performance in challenging environments.
