JTST-LED Small Size Intelligent Transmitter
ModuleJTST-LED, with the main body of
Microcontrollers CPU, is able to do logical operation and
programming. It combines analog and digital circuit in one machine,
so is able to output analog signal as well as digital
signal as per customer's requirement. Parameters configuration
and compensation can be done by adjusting programs to approve
accuracy grade of transmitters. Adopting HIRSCHMANN connector,
JTST-LED is transmitter, display, buttons and communication in one
and same device, and can be directly connected with piezoresistive
silicon sensor or ceramic piezoresistive sensor to be high
performance pressure transmitter. Thus it is more
cost-efficientProduction LineFeatures - Small Size Intelligent
Circuit Board with LED DisplayFour-bite high light LED
displayingTwo wires working mode provides sensors with two exciting
ways - constant current and constant voltage.Calibrating as per
full scale realizes bulk production and assures aging test time.
Easy to do temperature compensation, the complete machine accuracy
is better than 0.5% under -30~70ºCThree points calibrating,
complete machine accuracy better than 0.2%. Multi-point calibrating
is available as required.AD accuracy > 20 bits, DA accuracy
> 16 bits;Multi-functions as temperature compensation, small
signal wipes off, zero clearing and etc.On-site adjusting can be
done by bottons HIRSCHMANN connection Technical
