The document describes the features and characteristics of the product with brand CS and model CS3253 - 921.
The EDR‑N7 and EDR‑N7E are intelligent differential pressure transmitters that convert measured pressure differences into a high‑accuracy DC 4‑20 mA signal. They are suitable for measuring flow, level and pressure of gases, liquids and steam in various process environments, including explosion‑proof areas.
The sheet provides detailed technical data such as differential pressure ranges, accuracy, power supply requirements, load resistance, temperature limits, maximum allowable pressure and material construction. It also lists optional features like HART communication, digital indicator options, and various diaphragm and sealing material choices. This manual is written in Japanese.
| Differential pressure range (EDR‑N7, 800 reference) | 0.8–8 kPa |
|---|---|
| Output signal | DC 4–20 mA |
| Power supply voltage | DC 11.4–42.0 V |
| Load resistance (24 V supply) | 600 Ω |
| Operating temperature range | -20 °C to 85 °C |
| Maximum usable pressure (800 range) | 5 MPa |
They output a DC 4–20 mA current signal.
The devices operate from a DC supply of 11.4 to 42.0 V.
For the EDR‑N7 it is 0.8–8 kPa; for the high‑accuracy EDR‑N7E it is 0.098–8 kPa.
The transmitters can be used from –20 °C up to 85 °C.
