RFPulse101A脉冲计数器

RFPulse101A

The RFPulse101A is pulse counter and totalizer data recorder with built-in, wireless (RF) transmitter. Using the RFC101A receiver, the RFTemp101A can transmit data up to 120 feet, line of sight. Built-in memory also stores data internally. Can be used with dry contact switches and relays or analog voltage input signals from external devices (i.e. pulse initiators, pulse output transducers, totalizers, counters, flow meters etc.). Features user-programmable Engineering Units and fast data sampling rate.
