FAQ Section

Q1 :What measuring range does PT600 differential pressure transmitter support?

A: PT600 comes with a standard bidirectional range of -10 kPa to +10 kPa, and we support fully customized micro differential pressure spans for site-specific needs, including single-side ranges like 0–100 Pa, 0–500 Pa, 0–1 kPa, 0–5 kPa. The custom 0–500 Pa calibrated version is a drop-in replacement for the Setra ASL1005 series 500Pa transducer, matching all on-site pressure monitoring requirements for HVAC and cleanroom projects. All custom ranges maintain the base 0.2%FS measurement accuracy of the standard unit.

Q2: Can PT600 sensor output Modbus signal for PLC system?

A: Yes. PT600 offers Modbus RTU (RS485) digital output as a standard configurable option, alongside 4–20mA two-wire current, 0–5V and 0–10V three-wire analog signals. Its Modbus communication works seamlessly with mainstream industrial PLC, DCS and building automation controllers, supporting real-time pressure data collection, zero/span remote calibration and fault feedback. Unlike some imported transducers that only provide analog output, PT600’s multi-signal flexibility eliminates the need for additional signal converters during system upgrades.

Q3: Can PT600 fully replace the Setra ASL1005 500Pa differential pressure transducer?

A: PT600 custom-calibrated to 0–500Pa is a complete functional and mechanical replacement for Setra ASL1005MD1F11B3A00. It shares matching barbed hose process connections, 24V DC power supply and 4–20mA analog output that fits existing wiring and tubing without any mechanical modification. For projects delayed by long Setra factory lead times, PT600 can be produced and shipped within 2 weeks, with a unit price only one-fifth of the Setra ASL series. Multiple HVAC and fire engineering clients have fully standardized PT600 after emergency replacement deployments, citing equivalent on-site measurement stability and far lower total project cost.

Q4: What is the long-term stability of this micro pressure transmitter?

PT600’s long-term stability reaches ±0.2%FS per year under standard operating conditions, which meets the long-cycle monitoring demands of HVAC, fire protection and cleanroom equipment. The internal MEMS sensing chip and sealed isolation structure slow down signal drift effectively, requiring only annual routine calibration for most fixed installation scenarios. Field feedback from clients who switched from Setra ASL1005 confirms PT600 holds consistent readings for 3+ years of uninterrupted operation, with no noticeable deviation compared to the imported high-cost counterpart.
