Product Description
The internal chip of the PTM3051S monocrystalline silicon pressure transmitter adopts the MEMS monocrystalline silicon pressure chip imported from Germany. The sensor signal is converted into a standard signal output by a dedicated signal processing module. After long-term aging and stability screening, the product performance is stable and reliable. It is used in harsh environment and open air conditions., at the same time can be on-site pressure display, zero, full range, etc.
Features:
1. Using German imported MEMS monocrystalline silicon pressure chip.
2. Wide range coverage
3. Two-wire system, 4~20mA HART® protocol digital communication
4, Smart LCD screen head with backlight
5. Both remote transmission and local zero and span adjustment.
6. Full range, high precision and good stability.
7. Flameproof shell structure, strong anti-frequency interference.
8. No mechanical transmission parts, strong vibration resistance.
Application:
• Process control fields in industries such as petroleum, chemical, metallurgy, electricity, food, paper, medicine, machinery manufacturing, scientific experiment and aviation military;

• The product is installed vertically on the site pressure interface;
• When installing in the open air, the transmitter should be placed in a ventilated and dry place as much as possible to avoid direct light and rain, otherwise it will deteriorate the performanceor malfunction.
• When the product is installed in the thunder area, please indicate "lightning protection" whenordering. At the same time, it is recommended that users install lightning protection deviceson the site and ensure that the product and power supply are reliably grounded to reducethe probability of lightning damage to the transmitter.
• lf the transmitter is found to have no or abnormal output after installation, please check. a: Whether the electrical connection is accurate and firm; b: Whether the power supply voltage is too low and the load resistance is too large
