Waste Treatment Technology Temperature Sensor

Waste Treatment Technology is becoming a more important aspect in society for a number of reasons. Peak Sensors is involved with customers in a number of available technologies, and we are actively seeking new clients with novel waste technology developments to develop better temperature control sensors. If recycling options are exhausted or uneconomic, Turning waste into useful products has a number of advantages.

There are a number of proven and commercially viable waste treatment processes. The processes usually involves some degree of temperature control. Peak Sensors is currently collaborating with these waste treatment technology processes:

Gasification

Pyrolysis

Composting

Waste into Energy, High Temperature Thermocouples.… Read more

POX Temperature Sensor for Chemical Plants

Peak Sensors supplies temperature sensors to many specialised applications. POX, Partial Oxidation is a chemical plant process which uses fuel / air mixture to partially oxidise the gases into other useful products. Carbon Monoxide is the common product. The POX temperature sensor requires some novel design detail to survive the plant and to be safe should failure occur.

POX Process

This process occurs at temperatures around 1200 deg C. It is a very aggressive environment for temperature sensors. Heat, Pressure, Oxygen and Combustion products are present. A number of Probes are typically situated almost within the insulation to give them some protection. As insulation deteriates over the plant life the probes get an even tougher life.… Read more

Conduction Error in Temperature Sensors

Conduction error is a common problem for small application contact temperature sensors.

Temperature sensors can be very accurate devices, however poor probe design or bad installation can easily give a system significant temperature reading errors. Conduction error is primarily caused by inadequate immersion. Heavy Industrial applications usually have good immersions, but designers of small pieces of equipment must address the problem.

Sensors usually need protection sheaths and always use signal cables. Both items will conduct heat away from a system. Probe leads and sheath will pass through a thermal gradient at some point. If the thermal gradient is close to the measuring point, then the sensor will be influenced to some degree by ambient conditions.… Read more

Compost Temperature Sensor Design

Commercial Composting demands good temperature measurement and control. Elevated temperatures are required for throughput management and legal compliance. Compost temperature sensors are required for process management.

Compost Process

Temperatures of around 65 deg C are needed to optimise micro organism activity, accelerate organic matter breakdown, destroy pathogens and eliminate weed seeds. Low temperatures will allow anaerobic rotting to occur.

Throughput, process control and material handling are improved by using in vessel composting systems. Temperature sensors are inserted at strategic positions.

Compost Temperature Sensor design

The sensors have unique design features for this application. The temperature sensors get a rough tough life. Nothing seems to be delicate when making compost so probes must be very robust.… Read more

Aerospace Heat Treatment Thermocouples to AMS 2750D

Aerospace Heat Treatment applications require AMS 2750D thermocouples. The key point of this standard, for sensor makers, demands that Thermocouples are calibrated by approved means and shown to be within defined limits. Individual sensors or batches of Thermocouple material can be tested. The maximum acceptable error depends on sensor use. There are strict limits on the number of uses before recalibration or replacement is required.

Peak Sensors often supplies Mineral Insulated Thermocouples, Rare Metal Thermocouples or Thermocouple wire batch certified. Thermocouple type R, type S and type N are the most common aerospace sensors.

Cost Reduction for AMS 2750D

To minimise Mineral Insulated Thermocouple sensor costs, Peak Sensors will have batches of wire calibrated and then from it, build sensors according to a customers requirement.… Read more

Original Equipment Temperature Sensors

Many equipment designers require temperature measurement inputs in Original Equipment they are creating. Demands for thermal control, overheat protection, temperature compensation, heater and cooler switching all require system signals.

Working with Original Equipment Designers.

Peak Sensor staff are never happier than when we are talking to a design engineer about a new application. Engineers know their product well. Peak Sensors staff know about sensors. Put the two together and great solutions can emerge.

Good sensor design identifies the balance between a number of conflicting parameters

Probe Cost
System cost
Robustness
Protection from ambient conditions
Speed of response
Process connection
Accuracy
Sensor lifetime
Subsequent assembly
Replacement

Peak Sensors has a long history of working with designers to create optimal solutions for original equipment.… Read more

Temperature Sensor Selection for Design Engineers: Technology Review

Temperature is probably the most commonly measured physical parameter. Appropriate temperature sensor selection is essential. Designers have to decide on the best technology to employ considering the design brief. The sensor design comprises the employed sensor technology and the protection of the sensor from the process. This article covers the choice of temperature sensor selection.

Temperature Sensor Selection Technology Review

Each common technology has attributes:
