BTM-400plus 皮带张力仪 BTM-400plus 皮带张力仪 BTM-400plus 皮带张力计/皮带张力仪 概述 Supplied with both plug-in and cable-connected sensors 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. 特性 1. 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 2. Compact, easy-to-use design 3. Readings unaffected by nearby magnetic fields or noise 4. Displays tension in newtons (N) or pounds force (lbf) or natural frequency in Hertz (Hz) - selectable 5. Displays Menu in English, German, Spanish, Portuguese, French or Italian & others – selectable 参数 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 订货型号 Item Description Price BTM-400PLUS BTM-400PLUS - Belt Tension Meter Accessories BTMCAL Traceable Calibration Certificate with data BTM-PLUGSENSOR Spare LED Plug-In Sensor for BTM-400PLUS BTM-400-SENSOR Spare Cable-Type Sensor for BTM-400PLUS BTM-TFS Reference Tuning Fork set, 128 and 256hz, without certification CDT-TAPE 10 Strips of 1/2 x 4 inch reflective tape 订货清单 The BTM-400PLUS is supplied as a complete kit, including: the gauge, plug-in and cable connected sensors, 9-volt battery, Instruction Manual all in a foam-fitted, hard plastic carrying case.
