1. Description
The RT810 transmitters feature linearized output to temperature for RTD’s. It is
factory calibrated and designed for highest performance and lowest cost. The
wide temperature range and stocked availability make RT810 an excellent choice
for temperature signal transmission. A linearized output for RTD’s is a unique
performance feature of these transmitters.
2. Note
Prior to unpacking and installation, please read the operating instructions and
follow them carefully. These units are to be used, serviced, and repaired only by
individuals who are familiar with the operating instructions and the applicable
regulations for operational safety and accident prevention.
3. Control of Units
The units are calibrated and checked before shipment and shipped in good
conditions. If you detect a visible defect on the unit, we recommend that you
carefully check the packing material. In the event of a defect, please immediately
notify the mail service / freight forwarder, as they are responsible for shipping
damage.
