Coolant temperature sender

I changed the thermostat the other day and this hasn't solved my problem of the car not getting upto temperature like it should. I thought it was stuck open but up on checking both the new and old one they both performed the same, perfectly. And at £3 I cant complain that it wasn't that.

Now my next option is the coolant temp sender. I know this suffers from dirt/limescale build up on the probes but that wouldn't effect the reading would it? I dont get the beeping when I start it up, although I did when it had no coolant in when I changed the thermostat.

Could it be anything else?

Also I presume the car is fine to drive harder than when its cold as its actually warming up it's just getting a false reading on the dash?

I have seen the gauge hit 90 a few times. But most the time it hardlies moves or just sits at quarter.

Also I have searched but all you get is.....'al try the coolant temperature sender next'...and then there's no reply.

Things to check are the cooling fans stuck on? and is the top radiator hose hot? Also how hot does the heater inside blow out at?
