ELPRO Lepenik & Co. presents temperature sensors for compost, humus and silage materials from the range of special temperature sensor versions
One of our society’s main priorities is to focus on health and preserving a clean environment. This can be achieved by knowing that we are responsible for what we eat, as well as for nature. In doing so, we have a significant impact on our successors and on our surroundings. Looking after our health starts with the amount of unprocessed or locally produced food (preferably home-grown) that we eat. Caring for a cleaner environment starts in the shop, where we choose how much and what kind of waste we will have at home. It continues in our kitchen with waste separation. The environmental awareness of the population is increasing year by year. As a result, there is an increasing desire to be able to separate waste consistently.
Especially in rural areas and other places where there are houses with gardens, there is a lot of bio-waste. Today, bio-waste accounts for more than 25% of household waste. To reduce these, many people use home composts and humus. The latter have many positive effects on our health (the food we produce) and the environment. Not only can composting produce better crops, but composting also produces more fertile soil. Composting is the healthiest form of fertilisation because it is free of pesticides and other harmful substances and is completely organic or biological. Compost also increases microbial activity in the soil.
Temperature control is of paramount importance in the production and processing of compost. In this context, we present below temperature sensors for measuring the temperature in compost.
Composting is an aerobic decomposition process, so climatic conditions are a key factor in the processing or production of compost. The correct moisture, air and temperature of the compost must be taken into account.
The temperature in the compost heap can reach 70 °C. The micro-organisms that process the “food” – carbon and nitrogen from decomposed organic waste – also contribute to the temperature rise. If the temperature of the compost is not controlled, the organic matter will not decompose properly and the compost will not be usable. On the other hand, too much heat can dry out the compost, or even burn it.
Based on the above, the temperature in the compost must be carefully controlled. Competing temperature sensors have a high failure rate due to poor design and manufacturing, which is why we at ELPRO Lepenik & Co. found a reliable and cost-effective solution, more below.
The temperature pro be for temperature measurements in compost, humus, silages (silos) is one of ELPRO’s special versions of temperature sensors. The sensor is designed to be customised to the user’s desired length, with one or more temperature measurement levels. Most commonly, one level is measured, usually at the bottom of the tip. The sensor is robust, extra strong stainless steel so that it can be pushed into compost, humus or other silage layers with the T-handle. Using a robust design reduces the error rate.
Temperature sensors for compost temperature measurements are divided into two versions:
2230 4430 The needle-punch temperature sensor is based on thermocouple and is connected to industrial thermometers, e.g. TFN 520 – the most commonly used version.
The 2240 3740 needle-punch temperature sensor is based on a resistive sensor and is connected to precision thermometers, e.g. TFX 430 or TFX 420.
The two versions of the temperature sensors are visually similar, it is important to know whether they are fast and frequent measurements (2230 4430) or less frequent and precise measurements (2240 3740). In use, temperatures between -50 and 100 °C are common, but versions allow much more, so no temperature limits are imposed. The most common sensor lengths are 1000 mm, and in increments of 1000 to 6000 mm, with intermediate lengths available.
Both versions are customised to the user’s requirements, from the length and shape of the handles, connections, gauges(thermometer, datalogger, display, etc.). Adaptation does not mean paying more. These versions are always made to order and can be highly customisable, even in different price frames. The most important thing is results, reliability and longevity.
Industry temperature sensors come with a 5-year manufacturer’s warranty and are made in Slovenia.
From the temperature sensor range for smaller compost heaps or for home use, we offer the O350 3003/300/1000/M and the TFN 520 thermometer (there is another option) for connection to a thermocouple.
All temperature sensors can be made to your specifications and requirements. The most common designs are presented on the website, but in practice, production is mainly made to order.
At ELPRO Lepenik we are temperature and humidity experts for routine control and validation of various thermal processes.
The ELPRO Calibration Laboratory will calibrate your temperature sensors after they have been manufactured. calibrated and thus supplied with an accredited calibration certificate (SIST EN ISO/IEC 17025).
