Get Measurement You Can Depend on for Hazardous Areas with SICK Wire Draw Encoder

Sometimes, you need to measure the position of a moving part, but the machine is in a place where a normal sensor could be a big safety risk. In work areas that have flammable gas or dust in the air, you cannot use standard equipment because even a tiny electrical spark could cause a fire or an explosion. This special SICK wire draw encoder is a device that is built and certified to be safe for these very dangerous jobs.

The reason to choose this product is the trust that comes from a top brand and the right safety papers. SICK is a very well-known name for industrial sensors all over the world. This specific model also has the needed certifications like ATEX to prove that it is safe to use in hazardous areas which gives you peace of mind that your people and your equipment are safe.

Main Features for Safe Operation

This sensor has a number of parts that are made to keep it working safely in tough places.

• Explosion-proof Housing: The body of this sensor is built like a very strong sealed box. This means that if there was ever a small spark from the electronics inside the sensor, it could never get out and ignite any of the gas or dust in the outside air. This is the most important safety feature of this explosion proof position sensor. 
• Certified for Hazardous Areas: This SICK wire draw encoder is officially certified to specific international safety standards which makes it a true ATEX certified encoder.This certification is your proof that the device has been tested by a third party and is safe to use in places where there are flammable materials. It is a rating that you can trust.

• Precise Sensor: Even though this sensor is built to be very tough, it is also a very accurate measuring tool. It is a draw wire sensor for hazardous areas that will give you very precise and repeatable measurements of distance and position. The safety features do not make it any less accurate at its job.
• Clear Digital Communication: This is an SSI communication encoder which means that it sends its position data using a clear and dependable SSI digital signal. This type of signal is very good for industrial places. It is not easily messed up by any electronic noise from other nearby machines.

Frequently Asked Questions

1. What is a “Hazardous Area”?
   A Hazardous area is any place where there is a risk of an explosion because of flammable gases, liquids, or dust in the air. This includes places like oil rigs, chemical plants, and some types of mines. You must use special certified equipment in these areas.
   
2. What Does “ATEX” Mean?
   ATEX is the name of the European directive for equipment that is used in explosive atmospheres. If a product is an “ATEX certified encoder” then it means that it has been tested and approved to be safe to use in these specific hazardous areas within Europe and other places that follow these rules.
   
3. Is this Sensor Also Waterproof?
   This sensor has a high IP rating which means that its housing is very well sealed. This way it is protected from both dust and water. You can even check the product’s data sheet for the exact IP rating number to see how much water it can handle.
   
4. What is “SSI Communication”?
   SSi stands for Synchronous Serial Interface. It is a type of digital communication that is used to send information from a sensor to a controller. The simple and dependable way to send data is why it is so popular in industrial machines.
   
5. Do You Need a Special Cable for this Encoder?
   Yes, you should always use the correct type of shielded cable for any encoder to get a clean signal. For hazardous areas, you may also need to use specific types of cable glands and barriers to maintain the whole system safety rating. If needed, our team can provide you more information on this.
6. How do You Calculate the Displacement ?
   * Find the Numbers You Need: First, you need two numbers from your sensor’s data sheet. You need the total measurement range in millimeters (mm). You also need the resolution, which is the total number of pulses for one full turn (PPR).

   * Get the Pulse Counts: Next, you need to get the pulse counts from your machine’s controller. Write down the starting pulse count before the rope moves (we will call this X1). Then, write down the ending pulse count after the rope has moved (we will call this X2).* Do the Math: Here are two simple ways to do the math. For this example, we will use a sensor with a 500mm range and a 4096 PPR resolution.

   • Method 1: The Ratio Method This method uses a simple ratio. The math is: Length in mm = (X2 – X1) * 500 / 4096
   • Method 2: The Per-Pulse Method You can also first find out how much length each single pulse is equal to. To do this, you divide the total range by the total pulses: 500 mm / 4096 pulses = 0.122 mm per pulse
     Then, the math is: Length in mm = (X2 – X1) * 0.122
