Digital Gauss Meter
Digital Gauss meter works on the principle of Hall Effect in semiconductor. When a semiconductor with current flowing in one direction is introduced perpendicular to a magnetic field a voltage is produced at right angles to the current path. The magnitude of this voltage is proportional to the intensity of the magnetic field. This voltage is called Hall Voltage. This Hall voltage is amplified and calibrated as magnetic field.

Suspension Bridge Apparatus
DESCRIPTION:
Cables are frequently used to support loads over large spans such as cable stayed for suspension bridges, cable car systems and stadium roof. They are used extensively for permanent guys on structures such as microwave towers and derricks. They are also used for temporary guys during erection. The only force in a cable is direct tension. They are too flexible to carry any moment. A cable is used to carry concentrated loads, uniformly distributed load along its length and uniformly distributed load along the horizontal span. It takes the shape of a polygon under concentrated loads, a catenary under uniform load along its length (such as its own weight), and a parabola under uniform load along the horizontal span.EXPERIMENT:
• Study the Extension of each spring Balance Left & Right Both. • Study of the effect of a point loadTECHNICAL SPECIFICATION:
• Apparatus Consists of two mild steel cables 0.5cm diameter in cross section and 150cm long, pinned to two supports 90cm apart situated symmetrically. • One of the ends can be converted to a roller by applying a known load at the end with the help of suspended pulley system. • Vertical loads can be applied at various points along the span of the beam. • A dial gauge with 25mm travel (with a magnetic base) is to be supplied with the apparatus complete with a supporting stand and a set of weights.
Water Cooling Tower Apparatus
The apparatus consists of a forced draught, counter flow type-cooling tower. A blower supplies cooling air. Air enters the tower at the bottom. Hot water is, obtained from a geyser. Hot water is sprayed over the mesh packing through the nozzles and it flows downwards. Evaporative cooling of water occurs due to the current of air and water gets cooled. This student can study the operation of cooling tower and calculate the energy balance.
SPECIFICATION:
Cooling tower, fabricated of M.S. Sheets, 200 X 200 mm. cross section, 1.2m. height with Perspex front. Wire mesh packing is provided in the tower. Geyser – 3 Kw Capacity to provided hot water. Centrifugal blower, 1 HP capacity to force air through the tower. Multichannel Digital Temperature indicator to measure temperature at various points. Rotameter to measure inlet water flow. Measuring tank to measure outlet water flow. Calibrated orifice and water manometer to measure airflow. Arrangement to measure dry and wet bulb temperatures of air at 5 intermediate stations. A technical manual accompanies the unit. The unit Is provided with anticorrosion an attractive color powder coating.SERVICES REQUIRED:
440V, 32A, AC supply with neutral and earthing connection. Floor space of about 2m. X 1.5m. Water flow of 10 Ht./min. at constant head
