Ex-Zone Rated Sensors for Indian Hazardous Area Installations — Tippkemper-Matrix

If you’re specifying sensors for a plant area classified as Ex Zone 0, 1, 2, 20, 21 or 22 — a paint booth, a grain silo, an LPG bottling plant, a solvent recovery unit, a coal handling plant — the sensor choice isn’t really a preference, it’s a compliance requirement.

Tippkemper-Matrix GmbH has spent roughly 50 years building nothing but sensors for exactly this constraint, and Arush Switchgears LLP sources their range for Indian hazardous-area installations.

Why This Company Specifically

Tippkemper-Matrix is a German family-run manufacturer (with a Swiss manufacturing arm, Matrix Elektronik AG) that doesn’t make general-purpose sensors adapted for Ex use — Ex protection is the entire premise of the product line.

Their sensors are built around Ex d (flameproof enclosure) type protection and carry certification against international ATEX standards, IECEx, and UL recognition. The company is SWISO ISO 9001:2015 certified and runs a dedicated team of 50+ people across development, production and sales, focused entirely on this one problem.

Two related companies sit under the same umbrella and are worth knowing about if your requirement is more specialised:

• Tippkemper Elektronik GmbH & Co KG — develops and manufactures capacitive level sensors and high-temperature sensors specifically.
• Matrix Elektronik AG (Switzerland) — develops and manufactures the Ex-area sensor range, with Swiss distribution.

What You Can Actually Specify, By Sensor Function

Detecting Presence or Position (Photoelectric)

Photoelectric sensors and proximity switches (light barriers/light scanners) for object detection in Ex-classified areas — the most common requirement for conveyor and process line interlocks in hazardous zones.

Measuring Distance

Explosion-proof rangefinders and distance sensors — laser-based distance measurement rated for Ex use, relevant to level monitoring, stockpile measurement, and position feedback where a standard laser rangefinder isn’t rated for the zone.

Seeing Into the Hazardous Area

Ex-rated camera systems and light sources allow visual monitoring inside a classified zone without the camera itself becoming an ignition source. Paired explosion-proof laser pointers are available for alignment and targeting use in the same environments.

Getting a Signal Out of the Zone Without Electrical Risk

Light guides (with and without explosion protection) provide a mechanical/optical way to route a light signal out of a hazardous zone, sidestepping the electrical ignition-source question entirely for certain applications.

Detecting Metal Objects or Position (Inductive)

Explosion-proof inductive sensors — for metal object detection and position sensing inside Ex zones, a very common requirement in machine safety interlocking.

Machine Guarding / Interlocking

Safety sensors rated for hazardous area use — where a guard door, access panel or interlock needs to be monitored inside the classified zone itself.

Level Measurement in Demanding Conditions

High-temperature-resistant capacitive level systems — level sensing for silos, tanks and hoppers where standard capacitive sensors can’t handle either the temperature or the Ex classification, or both simultaneously.

This is the product line that runs through Tippkemper Elektronik specifically.

Non-Standard Requirements

A “special sensors” category exists for applications that don’t fit the standard product lines — worth raising directly if your requirement is unusual.

Powering and Switching the Above

Ex-rated power supply and switching devices are available to complete the loop, plus a general accessories range including mounting brackets, cabling and connectors sized for the sensor range above.

Where This Actually Gets Installed

• Gas and dust Ex zones (0, 1, 2, 20, 21, 22) — chemical plants, paint/coating lines, grain and powder handling, solvent processing.
• Harsh environments demanding penetration through dirt, fog or dust, plus general robustness and range.
• High-voltage areas
• Elevated-temperature areas
• Any area with safety requirements above standard industrial sensor ratings.

Getting This Into an Indian Project

The practical bottleneck with Ex-rated sensors usually isn’t finding a sensor that technically works — it’s finding one with certification your plant’s safety documentation and local inspecting authority will actually accept , landed with correct import paperwork.

Tell Arush Switchgears LLP your Ex zone classification (gas or dust, zone number), the sensing function you need (presence, distance, level, imaging, interlocking), and any temperature/pressure extremes in the area.

We’ll match it to the right Tippkemper-Matrix product and handle sourcing into India.
