BPK-III Pressure Gauge/Switch
Introduction:
The BPK-III series controllers are equipped with display, control,
and transmission functions, and have been widely utilized in
various automatic control applications. Their key features include:
1. Support for a wide range of input signals such as RTDS,
thermocouples, or standard signals (refer to the table). The
display range can be calibrated for nonlinear signals or set for
linear signals.
2. Isolated transmission output with 12-bit resolution that allows
for customizable scope settings.
3. Two relay outputs that support high/low, high/high-high, or
low/low-low alarm action types.
Specification

This product is made into 4 ~ 20 ma, or 0 to 20 ma output current
signal.If the user needs the voltage output signal transmission
output, it can be customized from the manufacturer or
self-connected 250 or 500 ohm resistors for 1 ~ 5V or 0 ~ 5V, 0 ~
10V voltage and resistance (note: the accuracy of the resistance
directly affects the accuracy of the transmission output voltage).
