TVN tension load cell

Product catalog summary
General Overview
The TVN tension load cell is designed for use with suspended hoppers for non-trade applications. It features a nickel-plated steel body, fully sealed by welded dishes, ensuring leak tightness according to IP 67 standards. The load cell is available in seven capacities: 50, 100, 200, 500, 1,000, 2,000, and 5,000 kg.

Description and Working Principle
The TVN load cell operates on the principle of measuring the deformation of a beam under shear force. Strain gauges configured as a Wheatstone bridge convert this force into an electrical signal.

Installation and Wiring
Mechanical Assembly: The load cell is mounted using two ball joints with lock nuts.
Electrical Assembly: The load cell outputs a low amplitude analogue signal, requiring careful electrical connections. Key precautions include connecting the shielding in the connection box or indicator, keeping cables away from electromagnetic disturbances, and protecting the measurement part from heat sources.

Technical Data
Dimensions and Weight: The weight varies from 0.580 kg for 50 to 1,000 kg models to 1.900 kg for the 5,000 kg model.
Mechanical Characteristics: Load limit is 150% of nominal capacity, and breaking load is 300%. Deflection under nominal capacity is 0.4 mm.
Electrical Characteristics: Recommended power supply is 10 V (max 15 V), with input impedance of 380 Ω ± 20 Ω and output impedance of 350 Ω ± 3 Ω. Insulation exceeds 2,000 MΩ, and sensitivity is 2 mV/V ± 0.1%.
Environmental Conditions: Operating temperature ranges from -10°C to +40°C, with a broader range without alteration from -30°C to +70°C. The load cell is IP 67 rated for leak tightness.

Optional Accessories
A set of two ball joints is available for tension assembly, suitable for different model capacities.

TVN tension load cell-1

Tension load cell -É Suspended hoppers for Non-Trade use only. The TVN load cell is composed of a nickel-plated steel body and is fully sealed by welded dishes. The TVN load cell is leak tight (according to IP 67) and compact. It is available in 7 capacities, namely : 50, 100, The principle used by the TVN load cell is measurement of the deformation of a beam to which a shear force is applied. It uses strain gauges installed as a Wheatstone bridge to convert the force into an electrical signal. Mechanical assembly The TVN load cell is installed using two ball joints with lock nuts*. Electrical assembly The load cell outputs a low amplitude analogue electrical signal. Therefore, some particular precautions need to be taken for the electrical connection. -É Systematically connect the shielding of the load cell in the connection box or onto the indicator. -É Keep the load cell cable away from elements that could cause serious electromagnetic disturbances. Avoid routing the power cable and measurement cable adjacent to each other. -É Keep the measurement part away from any heat source, or protect
