TEMPERATURE MEASUREMENT

ROUND UP

Stable at high temperatures

Plant safety is paramount in the chemical industry. Exact temperature measurement is thus indispensable, for example, in the boiler sump or feed.This is to ensure accident-free operation on the one hand but also to optimize plants and reduce downtime and maintenance.With the OPTITEMP series, KROHNE offers a wide range of temperature sensors that cover the needs of the industry and ensure maximum process reliability.Whether it is an aggressive medium, a high pres- sure or high flow velocities, as they are common in steam pipes, OPTITEMP sensors can withstand almost any load. This is due, among other things, to the special design: We are using exclusively mineral isolated measuring inserts. They are characterised by high accuracy, good long term stability and a high mechanical load capacity. Their ceramic connection block is sealed in a way that welding connections to the clamps are hermetically sealed and therefore excellent protected against corrosion. That helps avoiding failures and reducing costs over the entire life cycle. Available are standard thermowells following different standards as well as customised designs, welded multi-part types as well as bar stock types, with all common process connections. To resist

high chemical loads flange thermowells from stainless steel can be PTFE coated or protected with aTitanium orTantalummantle. Other characteristics include explosion protection thanks to intrinsic safety or an explosion proof design of the thermometer which contributes to the safety of the plant.

Wireless vibration and temperature sensor for superior machine monitoring RET Automation Controls is offering a wireless vibration and temperature sensor. Designed to effectively monitor machines for increases in vibration and temperature, the sensor measures RMS velocity inmillimetres per second or inches per second, and tempera- ture. This enables the sensor to identify machine problems before they become too severe and cause additional damage or result in unplanned down time.

The sensor is optimised to work with 1-wire serial radio devices, such as Banner’s wireless Q45VT Node, the P6 Performance Node and the Multi Hop M-H6 radio. Operators can easily set vibration thresholds based on the ISO 10816 standard.When a threshold has been exceeded, the wireless node can provide local indication, send the signal to a central location, and send the vibration and temperature data to the gateway for collection and trending. “Banner’s wireless sensor provides continuous vibration and temperaturemeasurements to quickly detect anymachine failure or potential problems,” said Scott Pritchard, director of wireless global sales, Banner Engineering. “This allows facil- ity managers to reduce labour costs by eliminating manual checks and the risk of human error.The wireless vibration and temperature sensor is ideal for a variety of machine monitor- ing applications, includingmotors, pumps, blowers andmany other types of machines throughout a facility.
