Abstract
A pressure derived type weighing device, is characterized in that a weighing hydraulic oil cylinder is communicated with a pressure conversion oil cylinder through oil circuits, a piston of the pressure conversion oil cylinder is connected with a pressure sensor; the pressure sensor is connected with a singlechip, a converter, a display device thereof. The weighing device has the good effects that 1. the weighing device is simple in structure, high in precision; 2. the weighing device reduces cost, the weighing hydraulic oil cylinder transfers the gravity to the pressure conversion oil cylinder, reduces the pressure, the pressure sensor of small range replaces the pressure sensor of large range, consequently which saves cost; 3. the electric digitalization is easy to read, receive for people.
Description
Technical field
The utility model relates to a kind of weighing device, and particularly a kind of pressure is derived the formula weighing device.
Background technology
CN88212503 has announced a kind of hydraulic mechanical type weighing device, it is characterized in that being connected and set up reading device in the pipeline with hydraulic oil in the oil cylinder, said reading device is exactly a hydralic pressure gauge (tensimeter), its defective is that the reflection sensitivity of hydralic pressure gauge is relatively poor, and the error of the weight of measuring is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, precision is high, the pressure of electronic digitalizing is derived the formula weighing device.
The utility model is made up of the hydraulic jack of weighing, pressure conversion oil cylinder, oil circuit, pressure transducer and electronic processing thereof, display device.
The hydraulic jack of weighing is communicated with pressure conversion oil cylinder by oil circuit, and the piston of pressure conversion oil cylinder is connected with pressure transducer; Pressure transducer is connected with its single-chip microcomputer, converter, display device.
Weight places on the piston of the hydraulic jack of weighing, gravity is converted to hydraulic pressure, pass to pressure conversion oil cylinder, pressure conversion oil cylinder directly acts on pressure transducer with pressure, after pressure transducer is stressed, change power induction into electric current, by electronic processing, display apparatus processes and be shown as numeral.
Beneficial effect: 1. simple in structure, precision is high; 2. reduce cost, the hydraulic jack of weighing is changed oil cylinder with weight transfer to pressure, and pressure is dwindled, and replaces the pressure transducer of wide range with the pressure transducer of little range, thereby saves cost; 3. the weight electronic digitalizing is easy to the people and understands, accepts.
