HBM T40B - Digital Torque TransducerRuggedness and precision - these are the characteristics of T40B, the digital telemetry torque sensor with magnetic rotational speed measuring system. T40B is based on the tried and tested T40 torque transducer and is convincing through many new features. The torque meter allows rotational speed measurement and, in addition, monitoring of the direction of rotation. An integrated optional reference pulse enables the angle of rotation to be measured, for example during functional testing.more...
HBM W1ELA-0 Inductive Displacement Transducer (Plunger)The type W1ELA/0-2 inductive displacement sensors are normally installed, for example in machines, test equipment and measuring instruments. The sensors are available with an accuracy class of 0.2 for 4.8 kHz carrier frequency. The sensors comprise the plunger and core unit. The principle of measurement of the W1ELA/0-2 sensors is based on the differential choke principle. The sensor body contains two measuring coils arranged axially one after the other, forming an inductive half bridge. This is supplemented in the carrier frequency amplifier connected to form a full bridge. The displacement measuring range covers both directions, starting from the zero position up to the nominal (rated) displacement. By moving the plunger, the inductance values of the two coils are changed. The difference in inductance is a measure of the displacement.more...
HBM C16-M Tank Weighing ModuleWhether for building industry tanks, coal bunkers or tanks for liquids and gases, the C16 weigh module has the specific properties required and is available for all applications. All the weighing modules, whether galvanized or made of stainless steel, are fitted with integrated stay rods to absorb the horizontal forces, such as typically occur with wind loads. Anti-liftoff devices are included in the design as an accessory and can be easily fitted by the user when required. The metrological heart of the module is the C16 selfrestoring pendulum load cell, which is available in various versions. Special features of C16 weighing modules: - Accuracy class D1, C3 or C4 under OIML - ATEX95 zones 1+21, zones 2+22 - FM approval (explosion protection for the USA) - Overvoltage protection - Digital output The weighing modules are available with maximum capacities ranging from 20 t to 400 t. This allows tanks of up to approximately 1,200 t, to be constructed and, subject to the design, also made legal for trade.more...
