Hospital Bed Weighing Scale
The Sensomatic hospital bed Weighing Scale makes weighing bedridden patients simple, gentle, and exact and is an indispensable tool in intensive care units. It can be used during dialysis, ICU and for bedridden patients to monitor overgrowth or check muscular dystrophy. Four measuring platforms can be installed easily and effortlessly under the bed's castors thanks to the integrated lifts.
The patient's precise weight is computed after subtracting the bed's previously determined weight using the pre-TARE function. A built-in battery offers power backup in the event of a power outage, allowing for continuous measuring. Sensotech provides high-quality Hospital Bed Weighing Scales all Over Globe.
Hospital Beds with Weight-Sensing System
A hospital bed has a system of load cells, a summing box, and a display to measure and monitor patient weight.
Load cells come in varied shapes and sizes. Planar, bending beam and shear beam are the most frequent types for hospital beds, and the best kind depends on how and where the load cell is attached. Shear beam and bending beam cells are commonly fitted between each caster wheel and its attachment point beneath the bed. Between the lower and upper bed frames, planar cells are frequently mounted.
The load cells in most systems are four, one for each corner. (In practice, depending on the size of the bed and the needed functionality, a hospital bed can have as many or as few load cells as desired.) The exact location of each cell is determined by how the bed is built and how the head and foot portions articulate.
The summing box, also known as a summing circuit, performs exactly what its name suggests: it collects the output from each load cell and adds them together. The circuit transmits the entire weight to the display panel, which is normally located in the middle of the bed. However, the summation box can be placed anywhere because it is not a force sensing mechanism, such as in the display or control panel. It’s a passive device.
The weight can be shown in a variety of ways. Weight information can be stored in a specialized unit at the foot, side, or head of the bed, or it can be integrated into the control panel of each bed.
Load Cell Types and Associated Technologies
Wheatstone bridge circuit
A Wheatstone bridge circuit has four strain gauges in its standard design known as a full bridge. However, some load cells have eight, sixteen, thirty-two, or even more gauges, and others simply have one or two known as a quarter or half bridge.
The performance of any load cell is determined by the correct location of the gauges, the mounting, and the materials utilized. The transducer's analog output is generally signal conditioned, amplified, and digitized before being shown.
Foil strain gauges
Reduced size, a variety of gauge patterns, encapsulated gauges, weldable gauges, open-faced gauges and temperature correction are all advantages of foil strain gauges.
Low production costs and the ability to mount on flat, curved, or slotted surfaces and inside holes allow creative design requirements. As a result, foil strain gauges are the most widely used nowadays
