General purpose, top-entry, constant current accelerometer with isolated AC output. Made from robust stainless steel throughout for long-term vibration analysis in harsh environments. Includes 19mm base, integral TNC connector, and available with a wide range of mountings. Smaller and lighter than MTN/1010. It uses coaxial cable (not twin core shielded like 1100, which also has internal shielding and isolated electronics) and thus shows lower immunity to electrical interference.
