The VP-201 detects the vibrations caused by the reciprocating motion of the engine's pistons. When combined with the proper tachometer the VP-201 maybe used to measure rpm on most 4-cylinder gasoline and diesel engines. Note: measurements are not possible on most 6-cylinder engines.

KEY
Blank => sensor is not compatible with tachometer Model # => sensor is compatible with tachometer using the specified cable model #
X => sensor is compatible with tachometer using integral cable
Note => sensor may be used with this tachometer with certain restrictions (see below)
Note 1: CP-Series Clamp-On sensors may be used with FT-1500 tachometer for diesel engine rpm measurements. In-line charge amplifier is required. Please contact us for details.
Note 2: IP-Series Inductive sensors may be used with the FT-1500 tachometer for rpm measurements on DC motors. Please contact us to discuss your application.
Note 3: A special modification is available for the SE-1520 tachometer that will permit the VP-201 or OM-200 sensors to be used with the SE-1520. Please contact us for details.
Note 4: The FT-1500 tachometer is capable of measuring the rpm of rotating equipment using sound or vibration sensors (e.g. it is possible to measure engine rpm from sound radiated by muffler). Please contact us if you would like to discuss your application.
