The Anritsu MW Series measures the surface temperature of moving wires, with roller sizes selected to match the wire diameter.
The Anritsu MW Series measures the surface temperature of moving wires. Choose the roller size to match the wire diameter, then select the thermocouple and connection for your measuring instrument.
Start with the wire diameter at the measurement point. If it falls on a boundary between two ranges, send the actual size and operating conditions so we can review the selection.
| Model | Wire diameter | Type K example | Type E example |
|---|---|---|---|
| MW-31 | 0.65–1 mm | MW-31K-TC1-ANP | MW-31E-TC1-ANP |
| MW-32 | 1–2 mm | MW-32K-TC1-ANP | MW-32E-TC1-ANP |
| MW-33 | 2–3 mm | MW-33K-TC1-ANP | MW-33E-TC1-ANP |
| MW-44 | 3–5 mm | MW-44K-TC1-ANP | MW-44E-TC1-ANP |
| MW-45 | 5–10 mm | MW-45K-TC1-ANP | MW-45E-TC1-ANP |
| MW-46 | 10–15 mm | MW-46K-TC1-ANP | MW-46E-TC1-ANP |

*Anritsu specifies tolerance on a stationary, flat, smooth metal surface. The response time represents 99% response on a flat, smooth metal surface. These test figures do not establish accuracy on every moving wire.
The sensing head temperature rating does not apply automatically to the grip, cable or plug. Durability depends on the application; Anritsu does not assign a standard service-life figure.
The previous Seacom listing identifies the following Type K replacement references. When replacing an older probe, send its full order code and application details to confirm the appropriate cable, connector and configuration.
| Earlier reference | Replacement reference listed by Seacom |
|---|---|
| MW-11K | MW-31K |
| MW-12K | MW-32K |
| MW-13K | MW-33K |
| MW-24K | MW-44K |
| MW-25K | MW-45K |
| MW-26K | MW-46K |
Confirm thermocouple and connector compatibility before pairing a probe with an instrument.
Contact Seacom Process Instruments Sdn Bhd with the wire diameter, material, speed, temperature range and instrument model. A photograph or drawing of the measurement point will help us review the arrangement.
