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.

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.
