The MWTC-A series has been discontinued. Please see the MWTC-D as a possible alternative or contact our Sales Engineering department.
The OMEGA™ MWTC-A Wireless Smart Thermocouple Connector Series features stand-alone, compact, battery powered thermocouple connectors that transmit
measurement data back to a mating receiver up to 90 m (300') away. When activated the connector will transmit readings continuously at pre-set time interval that was
programmed by the user during the initial setup.
Each unit measures and transmits: thermocouple input reading and connector ambient temperature to
a receiver and is displayed on the PC screen in real time using the free provided software. When used with an MWTC-REC receiver, data from multiple
wireless thermocouple connectors can be received and displayed. Each unit includes free software that converts your PC into a strip chart recorder or data
logger so readings can be saved and later printed or exported to a spreadsheet file.
The MWTC-REC series is a family of wireless receivers designed to work with the MWTC transmitters. Three models are available to meet your application needs, with either
USB communication to a PC, or analog output(s) to drive a remote display, recorder, data logger or PLC. Transmissions of up to 90 m (300') are possible with the MWTC.
The MWTC-REC1 is a compact multi-channel receiver that connects to your PC through a 1.8 m (6') cable (included). It is capable of working with up to 48 individual
MWTC wireless connectors.
The miniature MWTC-REC5 is designed for shorter distances, such as testing and laboratory applications. The size of a flash drive, the MWTC-REC5 plugs right
into USB port. The MWTC-REC6 is a compact, single channel receiver that provides an analog output that corresponds to the input range of the MWTC wireless connector it is paired to.
