NewswireTODAY - /newswire/ - Indore, Madhya Pradesh, India, 2007/03/08 - MPILC uses the RISC core micro-controller technology which makes it flexible and most reliable for measurement of level of liquids in tanks and homogeneous solids in silos in all process industries.

The new MPILC..sr. model uses two-wire pulse-coded (interference–free) digital communication between Sensor & Evaluation Unit. Signal can be transmitted up to a max. distance of 1 Km ( 25 Ohm/core ) from the Field Sensor.

Measured Level is displayed continuously on a multi-purpose 5-digit seven segment LED display for best possible resolution and better viewing from a distance.

The instrument uses Universal Power Supply (90 V AC to 265 V AC, 50/60 Hz) and provides 4…20 mA (Galvanically Isolated) output signal proportional to 0…100% level in the tank. This signal can be used for remote indication or control/annunciation.

In addition there are three independent set points which can be set over the entire range using 3-independent potential-free c/o contacts of relays which are integrated into the system.

It’s used extensively in Textile Industry in Dye Houses, Chip dryers, Polyester chips and other utilities besides Chemical, Pharmaceutical, Food stuff, F.M.C.G. industry segments.

The instrument has been specially designed keeping in mind the huge demand from the international market.

Salient Features:

Applications:

• Microprocessor based system for higher degree of reliability and stable operation in noisy environment due to intelligent digital communication between the electronic insert and
the evaluation unit.
• All parameters programmable via Five keys and Five multipurpose LED displays.
• Calibration possible without completely filling and emptying the vessel.
• Galvanically isolated 4 to 20mA output available for connecting to PLC.
• Three relays for programming three levels independently or as pump control logic. Three potential free change over relay output contacts.
• Built-in universal power supply for 90 to 260 V AC or 24V DC operation Suitable for continuous level measurement in conductive or non-conductive liquids, powdered or granular materials of homogeneous composition having stable dielectric constant.
Successfully used for monitoring and controlling the level in vessels containing water, oil, chemicals and foodstuffs in processing plants.

The measuring electrode and the container wall (or grounding probe) form an electrical capacitor with the material as the dielectric. A change in the material level of the container causes a change in the capacitance. This change is measured and processed by the microcontroller in the electronic insert and digitally communicated to the evaluation unit on a 2-wire interconnection. The advanced data transfer renders a noise free validated signal for further processing by the microcontroller in the evaluation unit. A galvanically isolated 4 to 20mA output proportional to the level change is available for connection to PLC, as also three potential free relay output contacts for signaling or control.
