AccuStar - 4 to 20mA Loop Powered Clinometer

AccuStar - 4 to 20mA Loop Powered Clinometer
AccuStar - 4 to 20mA Loop Powered Clinometer
Product Code : IP-66
Product Description

The AccuStar IP-66 is a 4 to 20mA loop powered clinometer specifically designed for industrial and outdoor applications. Rated to IP-66, the rugged die-cast, powder coated aluminum housing provides protection in the most hostile environments.

The heart of the system is our patented, capacitance-based tilt sensor with no moving parts. When rotated about its sensitive axis, this unique sensor provides an exceedingly linear variation in capacitance, which is then electronically converted into 4 to 20mA and VDC analog outputs proportional to the angular position. The AccuStar IP-66 may be operated as either a 2-wire loop powered angle transmitter, or a 4-wire analog output tilt sensor. Mounting features integrated into the die cast housing, make installation onto any vertical surface easy.

Also see our other models, AccuStar Electronic Clinometer (4 standard input/output configurations), AngleStar Protractor System (AccuStar with digital readout) and AngleStar DP-45 (handheld digital protractor).
