Level Transmitter Supplier in Ludhiana: Buying Guide

Key Takeaways

Ludhiana plants measure level in hydraulic oil tanks, quench tanks, coolant sumps and water tanks.
RB Automation supplies hydrostatic, magnetostrictive, ultrasonic, laser and switch-type level instruments to Ludhiana.
Hydrostatic RB21W suits water and coolant sumps; magnetostrictive RBL01 suits clean oil tanks.
Add a separate level switch for low-oil or dry-run protection on presses and pumps.

In Ludhiana, a level reading is usually about protecting a machine. A press whose hydraulic tank runs low starves and scores its pump. A heat treatment line needs its quench oil above the drop point for even hardness. The coolant sump under a CNC lathe or grinder must be topped up before the pump draws air. Then there are the overhead and underground water tanks every plant has, and the dye and process tanks of the hosiery trade. RB Automation is a level transmitter and hydrostatic level transmitter supplier for Ludhiana, sending contact and non-contact instruments from Ahmedabad and advising on the choice by phone, WhatsApp and email.

Tanks to Watch in Ludhiana Plants

Press oil and quench tanks: forging and fastener units at Dhandari Kalan, Sahnewal and Kanganwal need a continuous level on hydraulic reservoirs and quench tanks, plus a hard low-level trip.

Coolant sumps: machine tool and auto part plants in Focal Point and Industrial Areas A and B watch the sumps of CNC, grinding and washing machines.

Cooling water: rolling and steel units around Doraha, Khanna and Mandi Gobindgarh keep cooling pits and tanks at a safe level.

Dye and process water: hosiery dyeing and processing units monitor storage and process tanks, where a sensor that never touches the liquid can help.

Four Ways to Measure, Plus a Switch

Hydrostatic: RB XSENSE RB21W

The RB21W is a submersible probe that rests near the floor of the tank or pit. The deeper the liquid above it, the higher the pressure it feels, so its output follows the level directly. It is tough and economical, a natural choice for water tanks, coolant sumps, pits and bore wells.

Magnetostrictive: RB XSENSE RBL01

With the RBL01, a float rides up and down a stem and the transmitter reports its position finely and continuously. Clean oil reservoirs and storage tanks are where it shines.

Ultrasonic

Mounted above the surface, an ultrasonic level sensor times the return of a sound pulse and never contacts the liquid.

Laser

A laser distance sensor sends a tight beam, useful for bins, chutes and narrow nozzles.

Level switch

A level switch simply opens or closes at a set point, ideal for low-oil trips, overflow alarms and dry-run protection.

Every option is listed on the level sensing page.

Strengths and Limits

The hydrostatic probe is cheap per point and ignores foam or vapour on top, but it lives in the liquid. The magnetostrictive transmitter is the most precise, yet its float needs a fairly clean medium. Ultrasonic avoids contact but can be confused by steam, foam and internal pipes. Laser avoids contact too and copes with solids and tight openings.

Five Facts to Gather First

Depth of the tank, sump or pit, and the span you want to read.
What the liquid is: water, hydraulic oil, quench oil, coolant emulsion or dye liquor.
Its temperature, and whether there is steam, foam or splashing.
Where the sensor can go: through the top, through the side or hung on its cable.
Whether the PLC needs a 4-20 mA signal or just a contact.

A Typical Level Application in Ludhiana

Take a typical heat treatment line for hand tools or fasteners, where hot parts drop into an oil quench tank. The oil level must stay above the drop point, and the hydraulic press feeding the line has its own oil tank that must never run low. A continuous transmitter on the quench tank lets the PLC top up oil and warn before the level falls too far, while a magnetostrictive transmitter on the press tank shows the oil level on the HMI. An independent level switch on each tank trips the pump or press on low level, even if a transmitter or its cable fails.

Level Measurement Mistakes to Avoid

Fitting an ultrasonic sensor over a steaming or foaming quench tank.
Ordering a hydrostatic cable shorter than the real tank or pit depth.
Blocking the vent tube of a hydrostatic cable, which makes the reading drift.
Using a float probe in coolant that leaves sludge and deposits.
Relying on one sensor without a separate low-level or overflow switch.

Frequently Asked Questions

Which level transmitter suits a hydraulic press oil tank?

For a clean hydraulic oil tank, the RB XSENSE RBL01 magnetostrictive transmitter gives a fine continuous reading. Add a level switch as an independent low-oil trip. Share the tank height and oil temperature to confirm.

Which level instruments do you supply to Ludhiana?

We supply the RB XSENSE RB21W hydrostatic level transmitter, the RBL01 magnetostrictive level transmitter, ultrasonic level sensors, laser distance sensors and level switches, dispatched from Ahmedabad.

How does a hydrostatic level transmitter work?

It is lowered to the bottom of the tank or well and measures the pressure of the liquid above it. Because that pressure rises with depth, the signal converts directly into level.

Can I use an ultrasonic sensor on a quench or dye tank?

It depends on steam, foam and vapour above the liquid, which can disturb the echo. For hot, steaming tanks a contact transmitter is often more reliable. Share the tank conditions and we will advise.

What is the price of a level transmitter in Ludhiana?

There is no fixed price list. The price depends on the measuring principle, range, cable or probe length, output and quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com for a quotation.
