E-HELP: No Cabling Restrictions for FM Approvals on SIX

E-HELP: No Cabling Restrictions for FM Approvals on SIX
Q: I want to use an SIX Signal Isolator/Converter in a loop with a cable run of 1200’. Are there cable parameter values (i.e. maximum inductance/capacitance) that must be met in order to maintain the FM Non-Incendive certification?

E-HELP: Monitoring and Alarm Options for Gas Supply Valves

E-HELP: Monitoring and Alarm Options for Gas Supply Valves
Q: We have an existing Rosemount 1151DP tied to a Provox DCS. We also have a Moore Industries DDA 4-Wire Current and Voltage Alarm in the system to provide a Flow Switch Low and Flow Switch High interlock to our gas supply valves. Will newer products from Moore Industries provide more – or better – protection than the DDA?

E-HELP: Splitting and Isolating Output Signals to Passive Receivers

E-HELP: Splitting and Isolating Output Signals to Passive Receivers
Q: I need a 4-wire isolator and want to see if your MIT Multi-Channel Signal Isolator will work in my application. I have several 4-wire transmitters where I need to split and isolate the output signal to receivers that are passive (not powered). Will the MIT work provided that I supply 24Vdc power to the unit?

E-HELP: Differential Temperature Measurement with Two RTDs

E-HELP: Differential Temperature Measurement with Two RTDs

Q: I am looking for a differential temperature transmitter. We have used the SPT in the past and know that it will work, but I don’t know if you can use two inputs of two different 4-wire RTDs with the SPT.

A: The SPT has only four input terminals; therefore the number of RTD wires is limited. For differential temperature one RTD can be a 3-wire and the other RTD can only be a 2-wire. The lead length compensation wire of the 3-wire connection compensates for the lead length of both RTDs. This is only useful if you make sure that all five wires have the identical resistance.
