MWT-N Wireless Transmitter
Precision Instruments for Pressure, Flow, Temperature, and Level
The Meriam MWT (RF transmitter) and MWR (RF receiver) wireless systems are designed for rugged industrial applications where quick installation without conduit/wiring is required. The transmitter is housed in an explosion proof enclosure and is powered by 85 to 265 Vac. The receiver is enclosed in a DIN enclosure powered from 12 to 32 VDC. These devices are programmed at the factory per customer requirements. The user has the option to wire a discrete digital input via the ¾” NPT pipe connection on the transmitter, the output state is mimicked by the receiver. The outputs are selected and wired per user application: 4 to 20mA, 0 to 5Vdc, RS232, and 3 relay alarms.
The transmitters are available in four configurations:
- Explosion-proof battery powered
- Explosion-proof AC powered
- Explosion-proof DC powered
- DIN rail DC powered
Once installation is complete power is applied to the transmitter by turning on the power switch. LEDs can be seen through the glass radome to indicate the transmitter is working properly. The DIN rail receiver has LEDs to indicate power and data are being received properly.
