DIT Machines Laboratory has recently procured six RTW321 series of TorqSense sensors from Sensor Technology. Each device features two conventional analogue outputs and digital data display via RS 232 and USB ports.
The USB ports allow a connection to a PC that can additionally configure the operation. The device features an embedded self-diagnostic module that allows for accurate data supply and transmission. It alerts users when the speed or torque ratings extend the desired limit.
Five of these devices procured by the company have been installed on test modules used in university laboratories. One device has been kept aside for use in the upcoming research work. They have a torque range of 0 to 15 Nm, but have been configured for a maximum reading of 10 Nm so that students do not use them beyond the prescribed range during experiments. They determine and control speed from 0 to 1,500 rpm, and power from 0 to 1.4 kW.
Salient features of the devices include a large and secure overload margin, high accuracy and resolution, ability to operate uniformly in both clockwise and anticlockwise directions, and embedded temperature monitoring, making them ideal for deployment in laboratories.
