Motion Sensors, Inc. applies over 35 years of experience to provide customers with high quality custom sensors with reasonable prices and delivery. In addition to maintaining a line of standard sensors, a primary focus is on on providing custom or semi-custom sensors to meet specific application requirements. (read more)

It often happens that existing speed sensors are used in applications/environments that now require ATEX or CSA approval. Identification and testing of an alternative, certified sensor can be time consuming and costly. The Intrinsically Safe certifications at MSI allow for customization, providing the ability to design a fit, form and function equivalent to the legacy sensor. (read more)

Underwater sound measurements in the field often require hydrophones with built-in preamplifiers or they are connected to conditioning amplifiers that requires portable DC voltage supply. The EC6069 Battery Module supplies 18VDC from two exchangeable dry cell batteries. EC6069 is an ideal DC voltage source for hydrophones and for the preamplifiers VP1000 and CCA1000. (read more)
