FAQ：
Q1: What shipping methods do you use for pressure transmitters?
We typically ship via FedEx, UPS, or DHL. If you have a freight forwarder in China, we can also ship the goods to your forwarder free of charge.
Q2: Do your pressure transmitters support custom logos?
Yes, we can customize your company logo and company name on the nameplate. Full brand customization including housing logo is also available.
Q3: How is a pressure transmitter calibrated? How often should it be calibrated?
Zero-point and full-scale calibration are standard procedures. It is recommended to perform calibration every 6 to 12 months; for critical applications, this interval may be shortened.
Q4: What output signals are available?
The standard output is 4-20mA with HART protocol. RS485 Modbus is also available.
Q5: What is the accuracy of the YAY-3051?
Accuracy options: ±0.075%FS, ±0.1%FS, ±0.2%FS, or ±0.5%FS.
Q6: What explosion-proof ratings does it have?
Flameproof Exd IIC T4 with IP65 protection, suitable for hazardous environments.
Q7: What diaphragm materials can I choose?
Stainless steel 316L (standard), Hastelloy C, Tantalum, Titanium, Monel, and PTFE-lined.
Q8: What power supply is required?
DC12-36V, with 24VDC recommended.
Q9: What pressure types does it support?
DR (Micro differential pressure), DP (Differential pressure), GP (Gauge pressure), AP (Absolute pressure), and HP (High static pressure).
