Control Devices is pleased to offer their customers the new 0 to 10Vdc output version of the Penny + Giles SRH220DR dual redundant output contactless rotary position sensor.
With a low output signal noise of less than 1mVrms and an input/outlet delay of 3.5mS, the new SRH220DR rotary position sensor uses proven, non-contact programmable Hall effect technology to provide OEMs with highly reliable and accurate rotary measurement for factory automation and process control applications. It also has a choice of integrated six-way connectors and provides numerous factory-programmed options.
Designed for operation in extreme temperatures, the Penny + Giles SRH220DR dual redundant output contactless rotary position sensor enables system designers to quickly and simply improve the safety and integrity of control systems by using the dual independent power supply and output signals. This allows compliance with SIL-2 requirements for systematic safety as defined in IEC 61508.
Ideal for use in arduous environments, namely those of -40ºC to +115ºC, these rotary position sensors are suitable for applications in factory automation systems and process control machinery where a 0 to 10Vdc analog voltage signal is commonly used to monitor, control and record the status of equipment.
Unlike conventional shaft-operated rotary position sensors, the SRH220DR has an integrated shaft and magnet assembly that activates the Hall effect sensor through a hermetically-sealed chamber. This allows the sensor to be used in extreme environments subject to high shock and vibration, as well as endure immersion in fluids for short periods (IP68 protected).
The moulded housing of the SRH220DR rotary position sensor includes a crush-proof mounting flange detail with stainless steel inserts, allowing fitting and re-fitting of the sensor without damage to the flange. The housing also includes a choice of integrated six-way connectors compatible with AMP Superseal 1.5 or Deutsch DT06 profiles.
The configurable rotary position sensor provides numerous parameter options, including measurement range and clockwise or anticlockwise direction output; a flexibility that provides OEMs with greater control to configure the sensor to best suit their needs and achieve maximum performance
With the 0 to 10Vdc output option, the SRH220DR can now operate from a 13.5-30Vdc unregulated power supply and is available factory-programmed with any one of 341 different angles, from 20 degrees up to 360 degrees, in one degree increments. Furthermore, the Penny + Giles sensor also provides 12 bit resolution (0.025%) over the selected measuring range.
The addition of the 0 to 10Vdc to the SRH220DR dual redundant output contactless rotary position sensor further eases configuration, with factory-configured options also including analogue (0.5 to 4.5Vdc) or digital (Pulse Width Modulated) signal outputs as standard.
The SRH220DR can also be factory programmed to offer 0.1 to 4.9Vdc output range, matching the equivalent signals from a potentiometer and the two outputs can be used for error checking if they are set up to be opposed (clockwise on the first signal and anticlockwise on the second signal) and the output summed.
The Penny + Giles SRH220DR also features:
- electromagnetic immunity to 100V/m
- very low maximum output signal noise of less than 1mV
- class-leading non-linearity of ±0.4%
- stability of less than ±30ppm/ºC
- ptional lever arm kit where installation requires.
