Types of Thermal Sensor Cables
There are a variety of thermal sensor cable types. Listed below are a few common types. These types are Dydac, Molex, RTD, and Optical sensor mount. Each type is suited to a specific application. Once you have selected the type of cable you need, the next step is to determine what type of thermal sensor you need.
Dydac
There are several different types of cable for Dydac thermal sensors. These cables come in a variety of lengths and have different beta values to suit different applications. In addition, some cable types are UL approved. Others are customized and designed to suit the unique needs of the customer.
Thermocouple wires are typically available in Standard Limits and Special Limits accuracy. The Standard Limits accuracy allows measurements to be made from a range of 200 degrees to 50 degrees Celsius. The Special Limits accuracy is achieved by measuring the difference in temperature from a reference to a sensing end.
Molex
Molex offers many different types of thermal sensor cable assemblies that can suit a wide range of applications. These cable assemblies come with a variety of beta values, resistances, and lengths. In addition to this, you can also customize the cable assembly to fit your design requirements. You can choose between a ring terminal, thermal conductive epoxy, or Micro-Lock PLUS connectors.
Molex connectors are highly configurable and easy to use. These connectors have pins with a metal spring that locks into a nylon connector that has a plug and receptacle. The connectors are built with unique pin and socket designs, which allows you to swap out the pins without having to buy a new cable.
SM-EGT and PLX temperature sensor modules are compatible with these types of thermal sensor cables. These sensors are based on the SeMitec 104NT-4-R025H42G temperature sensor. The cable is 10 feet (3 meters) long and is made in the USA. The O2 sensor bung is M18 x 1.5mm pitch. It can be easily welded and is compatible with Bosch LSU4.2 and NTK/NGK L2H2 wideband oxygen sensors.
RTD
Thermal sensors can be connected to the temperature of a fluid using different types of cables. RTD cables are available in different sizes and are usually made from copper or another conductive metal. They are susceptible to electrical noise so it is important to purchase shielded or grounded cables to prevent interference. Some RTD cables are made from stainless steel or Inconel.
The simplest RTD thermal sensor cable types configuration has two wires. One is connected to each end of the element and the second is connected to lead two. The resistance of the circuit is then calculated by measuring the resistance of the lead wires. This leads to a degree of error, but this degree of error can be eliminated with the use of calibration. Another common configuration is the three-wire configuration. These three wires are of equal length, have equal resistance and errors, and are the most popular in industrial applications.
Another common RTD thermal sensor cable is the thermocouple, which measures temperature changes. It can also be used to measure flow rates and shaft speeds. It is also used to monitor oil and water temperature. There are various types of RTDs available, including thin-film and standard. In addition, each has different mounting options.
The resistance elements that are used in an RTD are made from various metals. The most common metal is platinum, which is the most accurate material to use. It is also resistant to corrosion and has a very long life span.
Optical sensor mount
There are a variety of options for optical sensor mount cable. For instance, you can choose between a single fiber or a multi-fiber optical cable. Depending on your application, you can choose from an array of fiber types, including plastic and glass fibers. Many of these types are flexible, are compatible with particular materials, or are temperature-resistant. In addition, you can choose from a variety of tip adapters, which can improve the sensing range and avoid unwanted reflections around the object.
If you are installing the sensor on a small space, you may choose a single-fiber unit. Single-fiber optical units are more flexible because they do not house the electronics. In addition, they can be shaped and threaded, making installation a breeze. They are ideal for small object detection and have adjustable focal distances. In addition, they are more suitable for long-range detection because they have a narrow beam, which reduces the possibility of deflection.
In addition to being flexible, a single-fiber optical sensor requires an optical sensor head. In addition to the optic sensor head, a fiber optic cable is also necessary for this type of sensor. This cable is flexible and has no electric circuits, so it is highly reliable even under extreme environmental conditions.
1-wire cable extender
The first step in making a 1-wire cable extender for thermal sensor is to solder an RJ45 socket onto the PCB. This chunky connector sits flat on the table, and needs to be soldered properly to avoid short circuits. Once the socket is soldered, proceed to test the connections.
When using a 1-wire cable extender for thermal sensor, you should keep in mind that it may interfere with the sensors, especially those with microcontrollers. These devices usually require a separate 5V power source. Additionally, the cable may not be long enough for the sensor to fully function.
A 1-Wire cable extender allows you to connect several 1-Wire devices to one LAN. Each device has a unique ID address. As a result, multiple smart thermocouples can be plugged into a single 1-Wire network, which can reduce costs and positioning.
A 1-wire cable extender is a useful device for extending the cable length for a thermal sensor. Generally, the cable must be 18 gauge or smaller with at least three conductors. You should avoid using shielded wire for long-term use as it tends to reduce the cable length. However, in some instances, a cat5e cable may be sufficient. However, the results will depend on your environment.
The polarized connectors are available in different configurations and models. They range in size from 0.75 sq. mm to 2.5 sq. mm and are suitable for applications in 65-155 C. They also come in plastic and metal shells. This makes them a versatile solution for various industrial and consumer applications.
