DT1 General Purpose Digital Thermometers

The Rototherm DT1 is a micro processor based, battery operated, continuous reading, type K thermocouple input digital thermometer.

Two basic versions are available, both have clear four digit LCD displays with 12.7mm high characters and 1ºC/ºF resolution. 4/20mA signal re-transmission and MAX / MIN temperature logging can also be incorporated.

The DT1-1 is a 316 stainless steel rigid stem temperature indicator. The stem can be either 12.7mm or 6.35mm diameter with a reduced tip for fast response. The stem length and fitting, if required, can be user specified. The DT1-1 can be mounted directly on to a pipe line or vessel where direct, local temperature indication is required.

The DT1-2 is a remote reading instrument, designed for mounting on a panel, either with a three hole front flange or a back flange for surface mounting. The indicator is connected to the sensor by a 3mm diameter stainless steel mineral insulated cable which can be fitted with a compression fitting if required.

DT2 Digital Thermometers

Using common construction to the DT1, the DT2 is a high accuracy, high resolution digital temperature indicator. The DT2 uses a precision three wire thin film PT1000 resistance element as a sensor and can be supplied in both rigid stem and remote reading variants. In common with the DT1 series the DT2 can be supplied with 4/20mA signal re-transmission and MAX / MIN temperature logging.

The DT2 -1 is a rigid stem, direct mounted instrument for local indication, stem configurations are common with the DT1-1. A special derivative of this product is the DT2-3, this is fitted with a 12.7mm stem with a reduced tip and a captive 3/4” or 1” BSP hygienic fitting – primary application are Dairy, Brewing and Food Industries.

The DT2-2 enables the measuring instrument to be mounted remotely from the sensor and is available in two variants with differing cable protection systems and sensor housings.

The standard instrument has a PTFE protected cable and a 6mm diameter, 50mm long stainless steel sensor housing. A cable gland can be supplied loose on the cable to enable a sealed connection to be made to tanks, pipes etc. Where cable protection is required 6mm diameter stainless steel armoured cable is available, the stainless steel sensor housing is 12.7mm diameter with a reduced tip, a standard compression fitting can be supplied either loose or captive

on the housing.

ATEX Approved Intrinsically Safe Versions

The addition to the range of an intrinsically safe version allows this product to be standardised in all Pharmaceutical and Petro Chemical industries.

Both Thermocouple (DT1X) and RTD (DT2X) sensor instruments are offered.

II 1G EEx ia IIC T4 (-20°C < Ta < +60°C)

DigiTemp Tx Transmitter

Any non intrinsically safe DigiTemp variant can be supplied as a two wire 4/20mA indicating temperature transmitter. Operating from a two wire DC power supply, the DigiTemp Tx can be configured during set up to re-transmit a 4/20mA signal across either the full, or part of the instruments measurement range. DigiTemp Tx is supplied with a 2 metre long connecting cable. Retransmission range must be advised at the time of ordering.

BL3

A range of surface mounting bimetallic thermometers suitable for testing, balancing and fault-finding on heating systems. They can be attached to a surface by an adjustable spring or magnet to give an immediate indication of temperature without drilling or cutting.

This range of bimetallic thermometers is equally suitable for use on pipelines or flat surfaces such as radiators, platens or hot plates.

Excellent thermal conductivity is provided by the aluminium housing to the bimetallic element, while the stainless steel case and bezel minimises dissipation of heat to the atmosphere.

BL3-01 Surface Temperature Thermometer attaches to pipes by means of a spring and rotating hook.Without the spring, the instrument can be used on horizontal surfaces.

A strong permanent magnet enables the BL3-02 thermometer to be easily attached to horizontal or vertical surfaces. It is ideal for checking surface temperatures prior to the application of special finishes.
