Q1: Parameter apa yang dapat diukur oleh XG3051DP?
A: This is a differential pressure transmitter that measures differential pressure at its core. Melalui konversi tekanan diferensial, ia dapat mengukur aliran pipa, level cairan wadah tertutup, perbedaan tekanan sebelum dan sesudah filter, dan tekanan negatif tungku. It is not possible to directly measure absolute pressure. When measuring flow, the HART square root function can be activated to output flow signals.
Q2: What is the reason for inaccurate transmitter output signal and large zero drift?
A: There are leaks, blockages, and fluid accumulation in the positive and negative pressure pipes; ② Kesalahan pengaturan migrasi jangkauan; ③ Perubahan suhu lingkungan secara tiba-tiba; ④ The membrane is subjected to overpressure impact. Prioritize checking the impulse piping and recalibrate the zero and range using a HART controller.
Q3: What are the precautions for XG3051DP two-wire wiring?
A: Mengadopsi sistem dua kabel DC24V, tanpa membedakan antara jalur sinyal positif dan negatif, beban sirkuit maksimum tidak melebihi 500 Ω; HART communication requires a circuit connected in series with a 250 Ω resistor; Strictly follow explosion-proof specifications for wiring in explosion-proof situations, and ensure reliable grounding of the casing.
Q4: What operating conditions require replacement of non 316L membranes?
A: Media yang diuji adalah media yang sangat korosif (asam kuat, alkali kuat, kandungan ion klorida tinggi), 316L akan menimbulkan korosi, dan perlu memilih lembaran film Hastelloy C, Monel atau Tantalum; Food and pharmaceutical hygiene conditions require customized hygienic membrane structures.
