The CHECK-LINE BTM-400PLUS accurately measures the static tension of flat, V and ribbed belts of rubber, leather, fabric and composite materials by measuring the natural frequency (Hz) of a segment of the belt that has been tapped and then converting it into tension units of newtons (N) or pounds force (lbf). The instrument uses a pulsed ruby red light source to measure the natural frequency of the vibrating belt. Unlike competitive models, the BTM-400PLUS is NOT affected by ambient noise, providing quick reliable results in all production and field applications. Features Includes two (2) separate Sensors – a plug-in type for one-handed operation and a cable-connected type for measuring belts with limited access space Compact, easy-to-use design Readings unaffected by nearby magnetic fields or noise Displays tension in newtons (N) or pounds force (lbf) or natural frequency in Hertz (Hz) - selectable Displays Menu in English, German, Spanish, Portuguese, French or Italian & others - selectable [custom1] Measuring Range* 3 - 800 Hz Accuracy** ± 5% or better Sensing Distance*** 0.200" - 1.6" (5 - 40 mm), typically (2.5"/60 mm max, depending upon ambient light & surface of belt to be measured) Casing ABS Plastic Display 2 line LCD, 16 character per line Input Range free span length: up to 9.990 m belt mass: up to 9.999 kg/m Belt Density Belt Density (d = kg/m or lb/ft) Belt Span Min, approx. 10 cm (4 inch) Max, no maximum (as long as belt will oscillate) Warranty 1 Year Light Source Red LED Light Size at 50mm - 6mm Square at 150mm - 15mm Square Power Supply 9V battery Metric Units MASS must be entered in kg/meter SPAN in "meters" English Units MASS must be entered in lbs/foot SPAN in "inches" Country of Origin Germany [/custom1]
