JCMT Multivariable Transmitter with temperature sensor

multi variable pressure transmitter JCMT is suitable to measure liquid, gas, or steam flow and differential pressure. RP1005 outputs a 4~20mADC / Modbus RS485 / HART / Pulse signal corresponding to the measured flow or differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored

Product Description

JCMT Multivariable Transmitter with temperature sensor 

The multi variable pressure transmitter JCMT is suitable to measure liquid, gas, or steam flow and differential pressure. JC1005 outputs a 4~20mADC / Modbus RS485 / Pulse signal corresponding to the measured flow or differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via different communications. Other key features include quick response, remote set-up using communications, selfdiagnostics and optional status output for pressure high/low alarm.

Zero Adjustment Limits

Zero can be fully elevated or suppressed, within the lower and upper range limits of the capsule.

External Zero Adjustment

External zero is continuously adjustable with 0.01% incremental resolution of span. Re-range can be done locally using the range setting switch.

Mounting Position Effects

Rotation in diaphragm plane has no effect. Tilting up to 90 degree will cause zero shift up to 0.4 kPa which can be corrected by the zero adjustment.

Output

Two wire 4~20mADC (Output range: 3.9 mA to 20.5 mA.),

Modbus RS485, HART FSK protocol on 4~20mADC signal,  Pulse signal output .

Failure Alarm (the mode can be selected)

Low Mode (min): 3.7 mA

High Mode (max): 21 mA

No Mode (hold): Keep the effective value before the fault. Note: The standard setting of failure alarm is High

Mode.

Response Time

The amplifier damping constant is 0.1 sec; The sensor damping constant is 0.1~1.6 sec, it depends on the range and range compression ratio. Amplifier damping

time constant is adjustable from 0.1 to 60 sec by software and added to response time.

UpTime < 15s

Ambient Temperature Limits
