Pentronic’s product range now includes a new rail-mounted signal converter for installation on a rail inside a switch cabinet, the PR 6437 from PR Electronics. It is a complement to the popular HART signal converter for terminal heads, the PR 5437.
The new unit is manufactured in several designs. It can be ordered with dual inputs and dual outputs, which means it can be used as a 2-channel unit to save space inside the switch cabinet.
Thanks to the dual inputs, which can serve as a redundancy function, you also have the possibility of achieving SIL 3. The unit can also be ordered with Marine approval.
As always with PR’s HART signal converters, there is a universal input which can measure both Pt100s and thermocouples, and which has good input isolation for disturbance-free measurement. The measurement accuracy and speed are the same as on the previous model, that is, ±0.04°C and 0.07 sec.
The PR 6437 can be mounted and function in ambient temperatures down to -50°C and up to 85°C.
