Model C801 “Tuff Tilt 420” Tiltmeter

The model C801 “Tuff Tilt 420” delivers the
same precision and durability of our A801, but
with 4-20mA output. Units are available in
single axis (uniaxial), and dual axis (biaxial) tilt
configurations. The Tuff Tilt 420 is current loop
powered, so tilt measurements are made using
an economical 2-wire pair, and because output
is 4-20mA there is no signal loss over long
cables. Units also include an on-board
thermistor for temperature measurements. All
units are rated IP65 waterproof for advanced
protection from the elements. Use the C801 for
structural monitoring, 4-20mA PLC systems,
industrial measurement and control, or
anywhere long cable runs are necessary.
