The SIKA DiTemp digital thermometers type 901-Ex, 902-Ex, 907-Ex work with a discrete-time process with one measurement cycle taking 3 seconds. The user can, consequently, read off the current temperature even in passing. A flashing activity symbol on the easily readable LED display indicates correct functioning of the instrument during the measurement cycle.

The DiTemp has an easily readable LCD. Two different types of display are available. The basic reasoning behind the design of the dual display unit was to give it the appearance of a traditional dial instrument. We achieved this with a circular arrangement of LCD elements. This quasi-analogue format enables you to interpret the reading as instantly as a conventional dial instrument. However, a 4-digit, 7-segment display is additionally incorporated for times when you want to know the exact temperature.

Instruments of the DiTemp series have a robust mechanical assembly and are designed for both industrial applications and use in harsh environmental conditions. The IP65 protection level (frontside) ensures these requirements are met. The immunity to electromagnetic interference satisfies the requirements of the current industry standards.

After switch-on, the instrument performs an internal self-test that includes a check of the connected sensor. Automatic diagnostic routines continuously monitor the sensor signal, and a broken sensor is indicated via the display unit. The microprocessor constantly tests the sensor signal for plausibility. In the event of a fault, the results are indicated on display as an error code.

Integration of the measurement transducer into the local display unit means the space requirement is substantially reduced along with acquisition and installation costs since a complete measuring point is saved. The measurement transducer system is independent of the local display unit, providing you with a redundant measuring system. The instrument is supplied via the transmitter, so there is no load on the battery or solar cell unless the current loop fails. This means the local display is both reliable and independent.

The absence of mechanical contacts makes the thermometer fail-safe and prevents unwanted switching operations through vibration, for example. In addition to the programmable alarm contact, the instrument has a signalling contact that indicates all faulty operating states such as a broken sensor or battery charge level. The contacts are designed as normally open contacts. Programming is performed without touching the instrument and is menu assisted. All operating states are monitored by the electronics. In contrast to mechanical instruments, the user has the benefit of a measuring system that is significantly more reliable und stable over the long term.
