Transportation of perishable goods: How to minimise waste
The transportation of perishable goods can be a challenge. To lengthen the storage life of perishable goods such as fruit and vegetables, they are often transported inside refrigerated containers where a controlled atmosphere (with reduced oxygen content) has been applied. Instrumental in maintaining this, is the acquisition of accurate data concerning the oxygen levels present on an ongoing basis. As a recognized specialist in advanced oxygen monitoring technology, SST Sensing has numerous products in its portfolio that are targeted at this specific application.
We can supply complete solutions for transportation of perishable goods for quick and simple installation. Alternatively, we can offer component parts that are easy to retrofit into existing systems.
Delivering elevated performance parameters is SST’s flagship Zicronia oxygen sensor offering. These products utilize our own proprietary technology, which results in improved precision and prolonged operation (as they do not become depleted) compared to conventional oxygen sensors on the market, as well as avoiding the inconvenience of using a reference gas. Furthermore, such devices are not prone to sensor drift over time, which means they do not need regular recalibration.
Achieving a 0.01% O2 measurement resolution and an accuracy of 0.5% O2, the highly popular Zirconia Oxygen Measurement System consists of one of these sensor devices accompanied by all the necessary supporting electronics. The OXY-LC interface board offers a fault tolerant RS485 Modbus RTU Protocol offers various benefits over other output types but most importantly it allows complete control of the sensor operation and access to all available information including sensor diagnostics, barometric pressure and pressure sensor temperature. All making them ideal for transportation of perishable goods.
The sensor is housed in a short probe with an M18x1.5mm thread, making installation quick and easy. The oxygen sensor can operate in temperatures ranging from -100°C to 250°C.
Targeted at cost sensitive system designs, our LuminOx range of fluorescence based oxygen sensors employ an innovative optoelectronics mechanism that allows them to serve as a suitable alternative for electrochemical devices, while providing considerable performance, logistical and ecological advantages.
These oxygen sensors exhibit 2% full scale accuracy, thereby outperforming any other oxygen sensor in their price bracket by a sizeable margin. An RS232 interface facilities integration. This means that they can supply an output direct to the connected system without any need for additional signal processing or data translation. Unlike competing electrochemical oxygen sensors, they do not contain any hazardous materials (so there are no issues associated with disposal). They also have significantly longer operational lifespans (at least 5 years).
