pump and valve innovator finds a test rig technology that talks the torque
T
o analyse the long- term performance and reliability of
its valves and pumps, Bifold has adopted torque transducers from Sensor Technology for its test rigs. Bifold is as innovative
in developing its tests as it is in advancing its product technologies. Engineer Andrew Laverick says: “We wanted to measure the power required to operate the valve, see how it changed over time and with long term use. The best way to do this was to measure the torque input. We used the TorqSense solution because the Sensor Technology engineers were so helpful and really knowledgeable about test rigs. As a test engineer you are almost resigned to long set up procedures and software issues. But Sensor Technology has designed these problems out of their TorqSense equipment, with the result that we were able to complete our tests well within the time schedule.” Bifold has since bought a second TorqSense for a new test rig that
assesses the performance of chemical injection pumps, used at oil/gas wellheads and on process pipelines. “This allows us to further develop our abilities to quickly provide bespoke equipment for ultra-demanding applications,” says Laverick, “safe in the knowledge that it will perform faultlessly over a long working life.”

module turns any sensor into a speed monitor
he new DP2122 mini-display module from ifm electronic transforms any sensor that provides a pulse output into a speed monitor with a
local display and two user-adjustable switching setpoints. Not only does this provide a versatile and cost-effective solution for a wide range of speed monitoring applications, it also greatly reduces the processing load on the control system PLC compared with using the PLC to directly evaluate pulses from the sensor as a way of determining speed. Typical applications for the DP1222 module include monitoring the
operation of belt and screw conveyors, fans, centrifuges, separators and other equipment where speed must be maintained within a specified operating range. Equally suitable for use with inductive, capacitive and photoelectric
sensors, the DP2122 module has an M12 connector which means that it can either be directly mounted on the sensor or connected to it with a standard cable. It provides two switching outputs which can be configured as normally open or normally closed, plus an IO-Link interface that provides continuous real-time transmission of the speed value. The IO-Link interface can also be used to configure the module, or alternatively setting can be carried out using the integral pushbuttons. The four-digit LED display provided by the DP2122 module shows the
current speed in green when this is in the range between the upper and lower switching points, and red when it is outside this range, thereby providing an instant visual indication of abnormal operating conditions. Separate LEDs are provided to confirm that the module is powered, and to show the status of the switching outputs. The module has an IP67 ingress protection rating and an operating range of -
25 to +60ºC, making it suitable for use in all industrial environments. ifm electronic
