Frequently Asked Questions
Q What pressure range does this transmitter support?
The transmitter supports a wide pressure range from 10 bar to 3000 bar. Custom pressure ranges are also available upon request to meet specific application requirements.
Q What output signals are available?
The transmitter offers three standard output signal options: 4–20mA, 0–5V, and 0–10V, making it compatible with a wide range of industrial control systems including SCADA, DCS, and PLCs.
Q Is this transmitter suitable for harsh or outdoor environments?
Yes. With an IP65/IP67 protection rating, a storage temperature range of −40°C to +125°C, and anti-vibration/impact-resistant construction, this transmitter is engineered for demanding industrial and outdoor environments. The 304/316L stainless steel housing also provides excellent corrosion resistance.
Q Does the transmitter require silicone oil filling?
No. This transmitter uses a dry-type sensing element with no silicone oil filling, completely eliminating the risk of oil leakage and media contamination — making it ideal for food, pharmaceutical, and environmentally sensitive applications.
Q Can the zero and span be adjusted in the field?
Yes. The transmitter is factory pre-calibrated for immediate use, but zero and span adjustments can be made in the field via internal potentiometers if recalibration is required during installation or maintenance.
Q What process connection options are available?
Standard process connections include M20×1.5, G1/4, G1/2, and NPT1/2. Custom process connections can be arranged to match your specific piping or equipment requirements.
