The Celesco SR1 Series of transducers, available from IDM Instruments , provides an off-the-shelf, rugged, low-cost, high performance linear position sensor solution that has been designed for wet environments and outdoor applications.
Originally designed for off-road construction equipment, the SR1 Series is now available in 3 different models: SR1M, SR1V and SR1A.
The SR1M provides a 4...20 mA linear position output signal over a maximum 125-inch full stroke range. The SR1M can be set for any range from a 0-125 inch stroke all the way down to a 0-25 inch stroke with the ease of simply pushing a button.
The SR1V has a 0-10 volt position feedback signal factory calibrated to the full 125-inch stroke. Just like the SR1M, the user can also easily rescale the output signal of this model to stroke ranges less than 125 inches.
The SR1A has a 10K ohm precision potentiometer to deliver a voltage divider signal over the full stroke range. As the stroke range of the SR1A cannot be rescaled like the other models, IDM Instruments currently offer two ranges: 62 inches and 125 inches.
Each SR1 model is an off the shelf transducer that comes complete with a versatile mounting bracket. The bracket provides multiple cable exit direction options for customers which allow it to be mounted to any vertical or horizontal service. The SR1 Series string pots (transducers) come with the universally accepted field installable M12 connector.
