'cost effective control device'

A temperature indicator is a very easy to use and cost-effective control device that helps to determine and display, e. g., the duration of exposure to excessive temperatures.

NRG GLOBAL MAKE Displacer type level switches offers the industrial user a wide choice of alarm and control configuration. DLS works on a simple buoyancy principle and is well suited for simple or complex applications, such as forming surging liquids or agitated fluids, and usually costs less than other types of level switches. CONSTRUCTION & OPERATION Operation is based on simple buoyancy principle. As the liquid level rises and progressively immerses the displacer elements, the effective weight suspended on the spring reduces and the consequent length of the spring change is used to provide magnet movement and operate the switch. The spring movement causes the magnetic sleeve to attract a pivoted magnet actuating a switch mechanism located outside the barrier tube. Built-in limit stops, prevent over stroking under level surge conditions. FEATURES: • Wide choice of switching functions • Suitable for large tanks up to 15 meters • Site adjustable switch points • Customized for high temp, high pressure & vaccum applications. • Reliable performance in turbulent liquids even without still pipes. • Easy transportation of longer length switches. • Enclosure : Weather proof-IP-65 Ex-proof-Gr.

Conductivity Level Switch is a simple, low cost, point level measurement switch designed for level detection of conductive liquids having low densities, high viscosities, containing solid particles and to detect interface between non-conductive and conductive liquids. The probes work through the variation of the electrical resistance between the reference electrode and the level-control electrode. Conductivity level switches detect the level resistance when their electrodes are covered by the medium. If the tank is made of plastic, concrete, or any other nonconductive material, an additional electrode is required as a reference Conductivity Level Switches are available with stainless steel 316 electrodes as standard Suitable for many chemicals and aggressive media which are conductive in nature and dirty liquids, liquids with high solid content Construction available with both Solid probes & Suspended probes to suit fitting requirement It is a simple, low cost, point level controller designed for detecton of conductive liquids, having low densites, high viscosities, containing solid particles and interface between nonconductive and conductive liquids. CONSTRUCTION & OPERATION It comprises of a probe, wired to a level controller. The probe holds one common reference/common electrode and one or multiple “Control Electrodes” depending upon the number of levels to be controlled. All the electrodes are suitably insulated to avoid electrical bridging. The lengths of “Control Electrodes” correspond to the height of preset level points to be controlled and the length of the “reference/common Electrode” is kept slightly longer than the longest “Control Electrode”. If tank is conductive, it can be used as a reference/common electrode. Then number of control electrodes equals number of preset levels. Level controller houses sensing electronics consisting of power supply and signal conditoning circuit which provide a “Low AC Voltage” across mass and control electrodes. On liquid reaching preset level point electrical circuit gets completed - generating a signal which is amplified to actuate a relay, those potential free contacts are available for subsequent operations. On “Level Falling” the circuit breaks, deactivating the relay Additional Information: Production Capacity: 100 Delivery Time: WEEK Packaging Details: EXPORT WORTHY PAKING

NRG GLOBAL MAKE side-mounted float level switch is suitable for liquid level control of open or bearing pressure container in industrial process. When the liquid level reaches to high or low limit, relay contact point can be as signal alarm device or the switch in electronic pump circuit. It is used in water treatment, petrochemical, furnace, shipyard etc. It is widely applicable in the condition of high viscosity, high pressure, high temperature because of it is flexible structure, and it can replace the UQK series products. Working principle To use of liquid buoyancy principle. When the floating ball due to buoyancy and moving up and down, the magnetic reed switch in the junction box will be action when it is influence by the arm end magnetic.

NRG GLOBAL MAKE Magnetic Level Gauges, MLG Series are in widespread use throughout process industries for local level indication of costly, corrosive and viscous liquids including water at saturation temperature in tanks or for interface applications in ambient conditions or under pressure and temperature conditions. Basically designed as an alternative to sight and gauge glass devices, the MLG is now commonly used in both new construction and plant expansion. The float guide pipe prevents sideways movements of float and also sudden movement of float due to turbulence. The level gauges have etched SS scale for level indication. These can be of two types: Flapper Type and Capsul Type. Magnetic level gauges are precision engineered and manufactured to indicate liquid level accurately, reliably, and continuously. These units are completely sealed and require no periodic maintenance. MLGs also eliminate vapor or liquid emission problems common with sight and gauge glasses.

Displacer controls offer alternative features to the float-operated control. The sensor is a weight (displacer), heavier than the liquid, that is suspended by a spring. When liquid contacts the displacer, a buoyancy force is produced, which causes the effective weight of the displacer to change. This causes the spring to retract slightly to a new equilibrium position. When the spring retracts, the attraction sleeve also moves upward into the field of the external magnet, thus overcoming the force of the bias spring and actuating the switching element.

NRG GLOBAL INSTRUMENTS MAKE are micro-controller based full bore type electromagnetic flow meters specially used for variousindustrial applications. These flow meters accurately measure the flow rate of conductive liquids and slurries in closed pipes. Due toits simple and rigid design, the flow meter is an obstruction less and maintenance-free instrument in place of conventionalmechanical flow measuring devices. The use of ‘Pulsed DC’ technology offers highest ability and better measuring accuracy in theform of electrical signal 4-20 mA DC linearly proportional to volumetric flow. The instrument is based on Faraday’s law ofelectromagnetic induction. A magnetic field is generated by the instrument in the flow tube. The fluid flowing through this magneticfield generates a voltage that is proportional to the flow velocity. Corresponding electrical output is provided with respect tomeasuring flow range
