Import Double Thermal Resistor Tr-501 — Buy in wholesale FOB from Supplier in China

Dongfang Yoyik Engineering Co., Ltd. produces the double thermal resistor model TR‑501 for use in power‑plant temperature monitoring systems. The component is a dual‑element resistor designed to provide precise thermal feedback in high‑temperature environments. According to the supplier’s catalogue, the resistor is manufactured in Deyang, Sichuan Province, China, under an ISO 9001:2008 quality management system. While the exact resistance value is not listed, the device is offered as a standard part for turbine and generator applications.

Typical double thermal resistors of this class are built from high‑temperature ceramic material and feature a resistance range of 0.1 Ω to 10 Ω. They normally exhibit a temperature coefficient of about 0.001 %/°C, allowing stable readings across the - 40 °C to +150 °C operating window. The TR‑501 can be mounted through‑hole on printed circuit boards, with a typical footprint of 30 mm × 15 mm × 10 mm. Such specifications align with common standards for industrial temperature sensing components used in steam turbine control loops.

Plant operators, OEMs and maintenance contractors are the primary purchasers of this resistor, seeking reliable thermal data for safety and efficiency. The supplier does not publish a minimum order quantity or unit price, so interested buyers should submit detailed specifications to obtain a quotation. Prior to contract, importers must verify the applicable Incoterm, expected production lead time and acceptable payment schedule with the factory. Requesting the ISO 9001:2008 certification copy and any type‑test reports will help confirm conformity to quality expectations.

Dongfang Yoyik Engineering Co., Ltd. is situated at 4‑3F, Building A, Huashan Platz, Deyang, Sichuan, China. The firm is recorded with a harbour‑level trust tier, but its public response rate is listed as 0 %, indicating limited recent communication data. It specialises in the production and supply of spare parts for power‑plant equipment, including steam turbine components and electrical sensors. The company highlights its commitment to “scientific management, continuous improvement, quality excellence and customer needs”.

In addition to the double thermal resistor, the catalogue lists a broad range of sensors, actuators and pressure transmitters. No specific certifications for the resistor beyond the ISO 9001:2008 system are disclosed. Prospective buyers should request sample units and test data to verify performance against their plant specifications.
