PRODUCT DESCRIPTION:

Libratherm offers six tank liquid level controller model LLC-06, designed to control the liquid level in the six independent tanks. It accepts 4 wire (3 + 1 common) of liquid level sensor in the form of potential free contacts for each tank to detect HI level, MED level and LOW level. Internal electronics circuit monitors the level from the level sensors and displays the status of each using the front panel LEDs. Two sets of 5A @ 230VAC relay contact output is provided for each tank, which can be used to control the Feed pump or the Delivery pump as per the users requirement. The controller operates on 230VAC supply and is available in 1/2 DIN size of 192 x 96 x 200 mm.

LLC-06 finds its application in the industries manufacturing breweries, aerated drinks, fruit juices, pharmaceutical syrups etc... where to prepare final product the different liquids are mixed from the different tanks and maintaining their level is a critical process. The controller featured here can maintain the desired levels of up to six tanks.

Our product SCR Firing and Triggering Cards using Phase Angle Control Technique For Single / Two or Three Phase heater control and DC rectifier. Using synchronized phase angle control technique.Libratherm offers SCR triggering cards model LTC-12, LTC-13 and LTC-15 and LTC-18 , which are designed to fire or trigger back to back connected SCRs using synchronized phase angle control technique. The card accepts analogue control signals of (0-5)/(0-10)VDC or (4-20)mA and provides proportional gate/cathode triggering pulses G1K1 + G2K2. These pulses can be used to trigger back-to-back connected SCRs upto 1000Amps with gate current upto 300mA. The card also provides built in regulated 5VDC supply to connect external potentiometer to manually control the SCR firing. The on card ramp up and ramp down settings allows gradual rise and fall of the voltage levels across the load. Many times it is required to limit the current flowing through the load. Such current limiting feature is available in LTC-13 – for single phase and two phase load. Whereas for 3 phase load, common three phase current limiting is achieved by LTC-18 card. The load current or Line current feedback is derived from the external CTs. This feature is useful for transformer load or inductive loads or for heating elements like Silicone Carbide and Molybdenum Disilicide, which exhibits significant change of resistance with increase in temperature. This feature will restrict the maximum load current to the value set using the on card current limit (CL) potentiometer. On a sudden increase in the current the current trip feature will over-ride the current limit feature and the firing of the thyristor will stop instantly. The trip contacts are available on the terminals.

Features:

• All these cards can be mounted inside the control panel.

• Digital and Linear circuit based.

• Smooth Control On card setting to adjust Ramp Up and Ramp Down.
