Import Bi-Metal Temperature Guages — Buy in Bulk from Supplier in India

Powertech Industries produces bi-metal temperature gauges designed for industrial temperature measurement across a span of -40°C to 600°C, as stated in the source data. The sensing element uses the differential expansion of bonded metal strips to drive a dial indicator, a well-established mechanical principle that eliminates the need for electrical power or external reference junctions. The stainless steel housing specified by the supplier provides a baseline level of corrosion resistance for chemical and process environments typical in Indian manufacturing clusters.

The gauge construction incorporates a protective glass cover over the dial face to safeguard the indicator mechanism from dust, moisture, and mechanical impact in plant conditions. Bi-metallic sensors of this type typically employ Invar steel paired with brass or copper-nickel alloys, though the exact strip composition for Powertech's units should be confirmed directly with the supplier. Standard industrial dial sizes for comparable instruments range from 63 mm to 150 mm, with 80 mm and 100 mm being common stock sizes in the Indian market. Accuracy classes for general-purpose bi-metal thermometers typically fall within ±1% to ±2% of full scale per EN 13190 or ASME B40.200, and buyers should request Powertech's calibration certificate to verify conformance.

These instruments serve process monitoring in chemical plants, petrochemical refineries, power generation facilities, and HVAC installations where local temperature indication is sufficient. Food processing and pharmaceutical applications may require sanitary fittings or 3-A certification, which the buyer must confirm with Powertech if required. The -40°C lower limit suits cold chain and refrigeration monitoring, while the 600°C upper ceiling covers most boiler and exhaust gas measurements. For import procurement, buyers should clarify whether Powertech supplies thermowells, compression fittings, or flange adapters as separate line items.

Powertech Industries operates from an address in the MIDC TTC Industrial Area of Turbhe, Navi Mumbai, Maharashtra, placing it within one of India's established manufacturing corridors with access to Jawaharlal Nehru Port for export shipments. The supplier tier is marked as 'imported' with a 'harbor' trust designation, which indicates the listing has passed basic marketplace verification but carries a response rate of 0.00% and an average response time of zero hours. Buyers should treat these engagement metrics as a signal to test communication channels before committing to orders.

The listing provides no stated employee count, year of establishment, revenue bracket, or named domestic or international clients. No ISO 9001, ISO 14001, or product-specific calibration accreditation is confirmed in the source data, and claims of ISO or CE compliance in the original description cannot be verified independently. Buyers are advised to request Powertech's quality management system certificate, scope of accreditation, and recent calibration records from an ILAC-accredited laboratory before finalising purchase terms.
