Model C904 “Clinometer Pak 420” The model C904 “Clinometer Pak 420” uniaxial clinometer delivers the same reliable performance as the A904, but with 4-20mA output. Units are available with longitudinal or transverse axis configuration. The C904 operates as a 2-wire 4-20mA current loop, and will drive signal over 1000m or more. Units also include an on-board thermistor for temperature measurement. Use the C904 with industrial PLC’s, platform position and control, geotechnical monitoring, or any application where long cables are required.
