Dialapak Temperature Controller

Overview

The Dialapak Temperature Controller series is a family of analog temperature control instruments manufactured by Honeywell, identified by the AVxxxx part number prefix. The series is dedicated entirely to temperature control functions in industrial process equipment.

The range includes standard temperature controllers, many in a 1/4 DIN panel-mount format, as well as dedicated high-limit controllers and percentage (0–100%) control units. Models cover a variety of temperature ranges and thermocouple/sensor types, including J, E, and T inputs, with spans such as −100 to +200 °C, 0–300 °C, 0–500 °F, and 0–600 °F.

Configurations

• 1/4 DIN temperature controls — panel-mount controllers across multiple ranges and sensor inputs
• High-limit controllers — including indicating and non-indicating variants
• Percentage control units — 0–100% control models

These controllers are commonly applied in process heating and industrial control applications where regulated temperature or high-limit protection is required.
