Pressure Transmitter (Analog Output)

Name: Pressure Transmitter (Analog Output)
SKU: rs-pm400-analog-output

RS PM400 is a high-pressure analog transmitter for full-scale ranges of 100, 160, 250 and 400 bar. It combines MEMS piezoresistive sensing with digital compensation, calibration and fault diagnostics.

Features & Applications:

The PM400 series is digitally compensated and calibrated using in-house algorithms and software to achieve:

Room-temperature accuracy ≤±0.1%
TEB: typical ≤±0.20% FS and maximum ≤±0.30% FS at −30 to 100 °C; typical ≤±0.30% FS and maximum ≤±0.50% FS at −40 to 125 °C.

Output modes

0.5-4.5 V ratiometric voltage
1-5 V, 0-10 V, 1-10 V absolute voltage
4-20 mA current, etc.

Media-contacting parts are made of SUS316L stainless steel and sealed by welding, with an optional built-in pulsation pressure buffer to ensure reliability and durability. The series offers IP67 or IP68 ingress protection as well as a high degree of EMI protection, and suits most application environments.

Product Highlights:

TEB: typical ≤±0.20% FS and maximum ≤±0.30% FS at −30 to 100 °C; typical ≤±0.30% FS and maximum ≤±0.50% FS at −40 to 125 °C.
Ingress protection depends on pressure reference, connectors and the complete assembly; see the specification table.
Compact design, size down to 22 A/F
Integrated pressure-buffer design; configuration depends on the order
Fault diagnostics function
