The MTL3046B performs a similar function to the MTL3041, but is tailored for use with ‘smart’ transmitters whose digital communication signals are superimposed on a standard 4/20mA analogue signal. The unit provides a minimum of 15V at 20mA to energise the transmitter while at the same time repeating the current accurately in a separate circuit to drive a load in the safe area. The transmitter can be calibrated, interrogated or tested from the host computer, or by using a hand-held communicator connected in either the safe or hazardous area. The MTL3046B is a development of the MTL3046, which it replaces, and it is compatible with the majority of ‘smart’ transmitters available.

OTHER APPLICATIONS OF MTL3046B

Although designed for ‘smart’ transmitter applications, the MTL3046B operates with standard analogue 4/20mA transmitters, and therefore can be especially useful if upgrading later to ‘smart’ transmitters. The MTL3046B can be used to repeat a current generated by hazardous-area equipment in an existing barrier-protected safe-area circuit, to provide a fully isolated output with a high load handling capability. The MTL3046B operating with an MTL3045 can pass measurement and control signals through a hazardous area separating two safe areas (see MTL3045). The frequency response of dc to 10kHz (hazardous to safe area) makes the MTL3046B ideal for some flowmeter applications such as vortex and turbine meters.
