PTL516S digital pressure transmitter

The PTL516S LCD digital pressure transmitter adopts the latest low-power microprocessor technology and advanced power management technology, with stable display and high display brightness. It has a built-in microprocessor and can be programmed with two buttons to achieve adjustable settings for zero point, full range, decimal point, display rate, and control point without any potentiometer adjustment. No external power supply is required, just connect it in series in the tested circuit to accurately display the 4-20mA signal in the tested circuit. Adopting imported specialized integrated circuits and manufactured using SMT technology, the circuit assembly density is high and the instrument size is small. Its outstanding advantage lies in its much lower pressure drop compared to similar products on the market. Highlighted 0.36-inch LCD display with 7 units to choose from, stable data display without jumping words. When the ultra-low working voltage is 20mA, it is less than 3.0VDC. Less than 2.5VDC at 4mA, the whole machine has ultra-low power consumption and fully intelligent working mode. Support user self calibration and non-linear correction of displayed values. Extremely low temperature drift, suitable for use in industrial environments at -30~70 degrees Celsius.

Widely used in industrial equipment, water conservancy, chemical industry, medical, electric power, air conditioning, diamond press machines, metallurgy, vehicle braking, and building water supply urinary catheter pressure measurement and control.

  • After-sales

    1. LONGLV provides customers with installation and debugging services, as well as other technical consultations. If necessary, technical personnel can provide on-site technical training. If the customer has any technical questions, the technical personnel will provide a response within 4 hours.
    2. LONGLV products are strictly designed and produced in accordance with the ISO9001 international quality system, with a 1-year warranty for sensor products and a 3-year warranty for instrument products, with a 7-day return and exchange policy and lifelong maintenance.
    (Human damage is not covered by the warranty, and customized products without quality issues are not returned or replaced.)
    3. For returns and exchanges caused by quality issues, Longlv will bear the return and exchange shipping costs. The cost of returns andexchanges for non quality issues will be borne by the customer.
    Note: Quality issues refer to customized parameters such as function, size, specifications, and installation method that are not customized according to customer requirements, do not meet functional requirements, have dimensional errors, and have inaccurate accuracy (excluding within the error range).
    Customized products require confirmation of drawings by both parties before processing and production. If the product does not meet customer requirements, a written objection must be raised within two weeks. If the customer does not raise an objection within the specified time limit, it will be deemed as qualified acceptance.
    If an objection is raised within the deadline and it is confirmed by both parties that it is a product quality issue or production has not been carried out according to the requirements confirmed by both parties, it can be exchanged or refunded. If there are no quality issues and the shipping model andthe contract signed model are complete and correct, no return or exchange service will be provided.
    4. The products returned for repair will have a test result issued within 3 working days and the repair will be completed within 7 working days.
