Laboratory grade accuracy, WiFi connectivity, Ruggedly built.
Get proven reliability, performance, and remote operation in a portable signal simulator for testing and calibrating sensor-driven systems.
The 1520 Precision Signal Simulator is a NIST-traceable signal source for testing and calibrating sensor-driven systems. This portable and easy-to-use system lets technicians bring laboratory-grade precision into the field or onto the factory floor or flightline. Applications include accelerometers, flow meters, pressure transducers, tachometer generators, and microphones. An intelligent sensor database lets operators simulate a wide variety of sensor types and build custom simulations using SQL queries.
MTI’s 1520 Precision Signal Simulator is Made in the USA and combines a rugged and ergonomic design with a battery that supports all-day use. This field-upgradable unit supports software updates along with additional sensors and features. Importantly, this WiFi-enabled device can be remotely controlled via a smartphone so that a single technician can perform troubleshooting and diagnostics. Technicians like its intuitive user interface and appreciate that its touchscreen is easy-to-use with a gloved hand.
