Contact Closure Pulse Input Adapter - 1 meter Sensor
Product Options
Overview
The Contact Closure Pulse Input Adapter connects sensors with pulse outputs to data loggers with smart-sensor inputs. This smart sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch-type of normally-open.
