Flanged Turbine Meters

Product Description

Pulsers: OD 01 - 02 - 03 - 04 Performance Data
High Frequency Pulsed Output Type: OPTO-01/02/03/04 Description: The OPTO-01 is a 2 -wire current switching device for use with the WP/D Cold Water Meters. The OPTO-02 is for use with WP/D Hot Water Meters (can be used for cold water applications if needed). This type of pulse is normally used for conversion to analog signals, (4-20mA) or inputs to high definition dosing/batching systems. Principle: Light pulses are transmitted by an IR light diode onto a reflector wheel. The reflections are picked up by two detectors in the sensor head and processed electronically. The micro-electronics are located in the capsule of the cable
Sensor Principle	IR-reflex light barrier acc. To DIN 19234, plug type
Specification	Supply voltage 8.2 Vdc Current with reflection < 1.2 mA Current without reflection > 2.1 mA Forward/reverse identification integrated by an additional current barrier at 1.5mA
Pulse Duration	Depending on flow in the meter At meter stop continuous pulse possible
Protection	IP 65 (DIN 40050)
Temperature Range	OD 01/03: ambient temperature < 70°C OD 02/04: medium temperature < 50°C
Connection Cable	Length: 3M (10 feet)
