COMMON QUESTIONS BEFORE ENQUIRING
Quick answers to common sourcing, customization, certification, and delivery questions before you contact our team.
What information should I include in my enquiry?
Please provide your required pressure range, output signal, process connection, order quantity, and specific application details, and our engineer will reply with a tailored solution within 24 hours.
What is your minimum order quantity (MOQ)?
We accept small trial orders. The standard MOQ for most pressure transmitters is 1-10 pieces, and we offer flexible MOQ for custom/OEM projects.
Can you provide OEM/ODM service?
Yes, we fully support OEM/ODM customization, including private logo printing, custom packaging, parameter adjustment, and private labeling for your brand.
What certifications do your products have?
All our products are certified with CE and RoHS. Specific models also support ATEX, IECEX, and other international certifications for hazardous area applications.
What is your normal delivery lead time?
For standard in-stock products, the lead time is 7-15 working days. For custom/OEM orders, the lead time is 15-25 working days, depending on complexity.
Can you customize pressure range and connection?
Absolutely. We can customize pressure ranges, process threads (G1/4, NPT, etc.), output signals, and electrical connections to match your application needs.
What is your warranty period?
We offer a 12-month warranty for all standard pressure transmitters, covering manufacturing defects and performance issues. Extended warranty is available for bulk orders.
Do you offer free samples for testing?
Yes, we provide sample orders for quality testing. Sample lead time is 3-7 working days, and sample costs can be deducted from your first formal bulk order.
What's the difference between gauge and absolute pressure?
Gauge pressure measures relative to atmospheric pressure, while absolute pressure measures relative to a full vacuum. We offer both types for different industrial applications.
What output signals do your transmitters support?
Our standard models support 4-20mA, RS485 Modbus, and Hart protocols. Custom output signals (e.g., 0-5V, 0-10V) are available upon request.
Can your transmitters work in harsh environments?
Yes, our products are designed for extreme conditions, including high temperature, corrosion, vibration, and explosive hazardous areas (with ATEX certification).
How do I get product datasheets and calibration certificates?
You can request datasheets and calibration certificates via the enquiry form, and our team will send them to you within 24 hours. We also provide third-party calibration reports.
What payment terms do you accept?
We accept T/T, L/C, PayPal, and Western Union. Flexible payment terms are available for long-term cooperative customers and bulk orders.
How do you ship international orders?
We ship via DHL, FedEx, UPS, and sea freight for bulk orders. We handle customs clearance and provide tracking numbers for all shipments.
Do you offer after-sales technical support?
Yes, we provide 24/7 online technical support for installation, troubleshooting, and maintenance. Our engineers will reply to your questions within 4 working hours.
Can you provide training for our team?
Yes, we offer free online training for product installation, calibration, and maintenance. We also provide on-site training for large projects upon request.
